* interfaces: Make fromInterfaceContractId pure.
This PR changes `fromInterfaceContractId` to make it pure. This means
it cannot verify the contract id coercion, and should only be used
with care. To balance this, this PR also adds `fetchFromInterface` which
combines a `fetch` with a `fromInterface` and `fromInterfaceContractId`,
to serve as a safer alternative to `fromInterfaceContractId`, and is more
useful than the old `fromInterfaceContractId` since it also returns the
fetched & converted contract payload.

Previously, all dependencies were installed first in a single step, and then
the data-dependencies were installed according to the dependency graph.
This failed for dependencies with data-dependencies since those are processed later.
This was achieved by installing _all_ dependencies and data-dependencies according to the
dependency graph. Additionally, to ensure that the instance-rewriting behavior is preserved,
the dependency graph is extended with edges from each data-dependency to the subset of
dependencies without data-dependencies.
[instance rewriting behaviour: the class instances from data-dependencies are rewritten
to refer to a matching class definition from a dependency when such a class definition exists.

* Speed up Daml repl startup
Daml repl startup is stupidly slow to the point where starting up and
executing 1+1 takes ~7s (piped to stdin so no typing included).
This PR speeds this up to ~4.5s. In addition to that, we also display
the repl process sooner and complete the last bit of setup while the
user is typing.
Specifically, we do the following:
1. Startup the JVM process in parallel with initializing our package
db and only block on it once it’s started (and remove a stupid 1s
sleep which doesn’t actually matter).
2. Load all packages in one go instead of one by one. This (roughly)
matches how the script service works.
3. Only block on packages being loaded once we start running the
script. Users can type before and we even typecheck their stuff
before.
We could take this further and do even more in parallel with users
typing but this seems to strike a good balance between implementation
complexity, UX (if startup actually fails you get somewhat sensible
errors) & performance.

List.foldl1 uses the first argument as the accumulator, whereas

The upgrade to node-fetch 3.x broke our vscode extension because it
can only be loaded from proper ES modules. I tried changing our
tsconfig to emit that but I couldn’t figure out how to make vscode be
happy with an es module extension. So in the end I gave up and stuck
with commonjs and downgraded to node-fetch 2.x which is still in
maintenance mode and gets bugfixes for now.
However that resulted in me finding a bunch of other issues: The
upgrade to new LSP versions resulted in our LSP server crashing on
messages sent by the vscode extension. So I had to upgrade the client
libraries as well to fix that which required upgrading typescript
as well as @types/vscode which forces a bump of the minimum vscode
version. 1.52.0 is from November 2020 so not that concerned but I’ll
let product know in case theyre worried.
With this change things now work correctly and the extension is
backwards compatible with SDK 1.18.0 which matches our usual approach
of trying to get users to install the latest version of the extension.

* damlc: Don't rely on polymorphic constant worker
Fixes https://github.com/digital-asset/daml/issues/12166 which was
caused by assuming that GHC would create a "worker function" for

no arguments. This only caused a problem with partially applied
constructors, so, it only applies to zero argument constructors of
polymorphic types in situations where the type argument is eta-reduced.

Since Scala 2.13.2, Scala introduced built-in support to
manage warnings in a more granular fashion, thus making
the silencer plugin we are currently using no longer
strictly useful. Removing compiler plugins also removes
friction from migrating to Scala 3 in the future. As a
cherry on top, the built-in warning configuration also
allows to check whether a `@nowarn` actually does
anything, allowing us to proactively remove unused
warnings should the need arise.
[Here][1] is s a blog post by the Scala team about it.
Warnings have been either solved or preserved if useful,
trying to minimize the scope (keeping it at the single
expression scope if possible). In particular, all
remaining usages of the Scala Collection API compatibility
module have been removed.
Using the silencer plugin also apparently hid a few
remaining usages of compatibility libraries that were used
as part of the transition from Scala 2.12 to Scala 2.13
that are no longer needed. Removing those warnings
highlighted those.

The problem with envEmptyInterfaces is that it can only detect
interfaces in the current module. When you try to implement an
interface across a module boundary, LFConversion has very little
information about the interface.
This PR removes envEmptyInterfaces and simplifies the code
that used it, so it works uniformly for all interfaces
regardless of how many methods it has. The alternative would be
to pass more information into LFConversion, but this seems simpler.

* Add type rep argument for interface exercises.
(Still WIP.)
Part of #11703. Fixes the order in which errors are raised ("wrong type"
takes priority over "does not implement interface"). This PR also simplifies
ExerciseInterface by making the guard mandatory, otherwise there's too
many variations. We can revisit that later if we want.

* Split daml-lf encode/decode Haskell libraries
I was working on limiting the supported input versions in damlc. This
requires the list of stable package ids so we can allow those to be
decoded even if they are older.
However that leads to a cyclical dependency:
To get the package ids of the stable packages, I need to encode
them. The version check is in the decoder. If those live in the same
package, I now end up with a cyclical dependency and
Bazel (understandably) gets very sad.
This PR splits decoding/encoding into two libraries with the
generation of stable packages only depending on encoding.

* Drop a deriving MapKey

* Add a guard when exercising by interface.
This fixes part of #11703, when exercising an inherited choice by
interface and you know the template id, via the command preprocessor.
It does this by inserting a "guard" in between the interface fetch and
the exercise body. The guard is a function Interface -> Bool, which
is general enough to check the template id, without complicating too
much in speedy. And can be generalized in the future to check more,
like signatories, etc.
I added the guard as an optional argument to UExerciseByInterface.
This isn't hooked up to the protobuf AST yet (or Haskell side for
that matter) -- but I'll do it in the next PR! For now you can invoke
the guarded exercise via the command preprocessor, so I can enable the
approprate engine tests. (There's still some failing fetch tests left,
but I decided to leave this for later. Fetch can be a lot simpler than
guarded choices, since you always add a fetch node. No need for fancy
continuations.)

The precision of `Instant.now()` increased between Java 8 and Java 9.
On Linux and MacOS this doesn't seem to be a problem, as the precision
still seems to be at micro seconds. However, on Windows this now causes
errors of the following form:
```
java.lang.IllegalArgumentException: Conversion of Instant
2021-11-05T13:58:56.726875100Z to microsecond granularity would result
in loss of precision.
```
Suggesting that it now offers sub-microsecond precision.
`TimestampConversion.instantToMicros` had a check to fail if the
conversion lead to a loss of precision. In the specific failing test
case this is not a concern, so this adds a `roundInstantToMicros`
variant that avoids this kind of error.

* interfaces: Preserve by_interface data for create.
Part of #10915
This was a lot more involved than fetch or exercise. The first issue is
that we need to preserve the interface id into speedy, so it needs a
separate primitive ("experimental" won't cut it). Second, because
speedy's create requires the template definition, and now the interface
id as well, we basically need to compile a separate version of "create"
for each interface that a template implements, hence the separate
`CreateByInterfaceDefRef(templateId, ifaceId)`.

We’ve seen the tests time out despite already having a 900s test
timeout so this PR speeds up the tests using the following approaches:
1. Drop redundant test. We don’t need a test to test that daml repl
starts without a ledger if other tests also use that. Admittedly that
could make debugging slightly worse but I’m happy to accept that here.
2. Stop using a Ledger where we don’t need one. The import tests are
about testing the client side not the server side.
3. Share ledgers where we can. The inbound messages size tests and the
static time tests can reuse the ledger.
4. Stop using packages where we don’t need them. This speeds up both
ledger startup as well as Daml Repl startup.
