* Limit memory usage of scenario service in tests
Previously the scenario service used over 2GB of memory during
//compiler/damlc/tests:integration-dev for absolutely no reason.
This PR adds an option to pass JVM options when starting the scenario
service and sets them to 200MB for the Shake tests and the damlc
integration tests which seems to be more than sufficient.
These option can also be set in `daml.yaml`. I did not change the
defaults since this is shipped to users where I’d rather have high
memory usage than a crashing scenario service and on certain large
DAML codebases we might actually use a fair bit.

* Replace unstable-types tests by a Haskell test suite
The JQ based test suite is absurdly slow, it takes around 60s to run
on my machine. The Haskell test suite on the other hand takes less
than 2s on my machine so this is a speedup of over 30x and I have to
read less bash.

* Address review comments
- Move deployment tests (deployTest, fetchTest) out of integration-tests.
- Use DA.Test.Sandbox where appropriate.
- Split out code for useful test patterns: i.e. calling commands quietly, getFreePort.

The details are in a comment since I want to preserve them. Please
review carefully, I don’t trust my async exception foo.
This is only an issue in the integration tests I believe since we
change files of interest all the time. As long as you stay stable at
some point for some amount of time, we will GC properly either way.
In my tests, this reduces memory usage of the scenario service in the
integration tests from 3 to 2 GiB. There is sadly
anther leak somewhere (contexts are properly GCd now, I verified that
we never have more than 3 contexts in the server). I’ll do some more
investigation but memory grows linearly to the 2GiB while it should
stay pretty much constant.

* REPL server print error messages

* Improve handling of exposed-modules with data-dependencies
Previously, we tried to rename all modules of a dependency via
--package. This fails if some of those modules are not exported. This
was trivial to hit as a user since the ``daml-trigger`` library made
use of this.
This PR adds a few things to improve the situation:
1. We only rename modules that are exposed. This fixes the issue if
you don’t actually reference a non-exposed module from your
data-dependency.
2. I’ve removed the exposed-modules from daml-trigger. I don’t think
they are essential here given that the module name has `Internal`
in the name and it’s too easy to have something that actually
references the non-exposed module since the types are reexported.
3. I’ve added documentation that mentions this issue.
4. I’ve added a warning if your exposed-modules are excluding some
modules. Maybe worth turning this into an error in the future.

Until #5294, we had some test cases for `damlc` flying around there
were never run because they had an upper bound on an unsupported
DAML-LF version. This PR makes sure we'll clean up such test cases in
the future.

* Turn warnings for module name/record name mismatches into errors
The module name warning existed for ages. We started warning about the
record name mismatch in 0.13.55 so I’d like to turn it into an error
before 1.0
changelog_begin
- [DAML Compiler] File names must now match up with module names. This
already produced a warning in previous releases.
- [DAML Compiler] It is now an error to define a record with a single
constructor where the constructor does not match the type
name. To fix the error you need to change ```data X = Y { … }``` to
```data X = X { … }```. This restriction only applies to
single-constructor records. Variants and enums are not affected.
This already produced a warning in 0.13.55.

Adding more syntax is just confusing for beginners so these are not
particularly helpful and I would argue that they aren’t that useful in
general even once you move past the beginner stage.

* Make name collision check more strict
This PR extends the name collision check to catch collisions between
A:B (type B in module A) and module A.B.C. For now this is just a
warning and not an error. Once we turn it into an error, we also need
to add this to the Scala collision checker.
There is a fair bit of plumbing required to make warnings work but on
the plus side we get multiple errors at once now instead of erroring
out on the first one.
changelog_begin
- [DAML Compiler] The name collision check has been extended to also
count the case as a collision where you have a type B in module A and a module
A.B.C (but no module A.B). This is a warning in this SDK release but
will become an error in a future release. The typescript codegen is
not usable on packages that don’t uphold this restriction.

This PR adds as `ScriptLedgerClient` trait (happy to change the name
if anyone has a better proposal) that abstracts over the interaction
with the ledger. This will allow us to plug in a different
implementation for interacting with the JSON API so we can run DAML
scripts against DABL or other environments where gRPC is not a
workable option. Note that this PR does not yet add the implementation
for interacting with the JSON API. I’ll leave that for a separate PR.

CHANGELOG_BEGIN
- [Ledger API] DAML ledgers have switched to a new ledger time model.
The ledger_effective_time and maximum_record_time fields of command submission are deprecated,
the ledger time of transactions is instead set automatically by the ledger API server.
Ledger time is no longer strictly monotonically increasing, but only follows causal monotonicity:
ledger time of transactions is greater than or equal to the ledger time of any used contract.
See `#4345 <https://github.com/digital-asset/daml/issues/4345>`__.

Fix daml2ts tests
This PR bumps ghcide, haskell-lsp and haskell-lsp-types. There aren’t
really any important changes in ghcide itself but the haskell-lsp
update includes my fix for crashing completions.
One change in ghcide itself is that NormalizedFilePath got moved to
haskell-lsp. ghcide needs special treatment for empty file paths so we
use `toNormalizedFilePath'` from ghcide instead of
`toNormalizedFilePath` from `haskell-lsp`. I’ve added an hlint rule to
enforce this.

* Fix tests
* Support complex patterns in DAML REPL
Previously, we only supported simple variable patterns in DAML
repl. This PR extends this to support pretty much all patterns. The
main complexity here is in handling shadowing correctly but I’m
reasonably confident the solution here is sensible.
What doesn’t work properly yet is partial patterns. I’ve added a
comment describing the issue and a potential solution. Given that this
isn’t a regression apart from maybe a slightly worse error message, I
think it makes sense to merge this PR and fix that separately.

- [DAML REPL - Experimental] You can now use more complex patterns in
