* telemetry: use an extra cache directory for telemetry
If the sdk's `.daml` directory is not writable, telemetry fails and
kills the IDE. We add a new assistant environment variable "DAML_CACHE".
If set, this directory is used for telemetry cache data.
Fixes#8396.

CHANGELOG_BEGIN
- [Daml CLI] Three options that were never meant to be public are now
hidden from the output of various `daml xxx --help` commands. The
options still have the same effect when present, so this is not (yet)
a breaking change. Using these options tends to result in very
unhelpful, when not outright broken, dlint configurations, so we expect
existing usage to be low to nonexistent. If you do use them please
share your use-case with us. The options are:
- `--with-dlint`
- `--without-dlint`
- `--allow-overrides`

* Remove redundant list of LF versions
After #8472, I realized that there must be a list used for daml-stdlib
and daml-prim already and it turns out there is. I’ve removed that one
in favor of the one added in #8472 since I like having all in one
place and the one from #8472 is created by filtering an existing list
instead of creating a completely separate list like we do here.

This PR updates scalafmt and enables trailingCommas =
multiple. Unfortunately, scalafmt broke the version field which means
we cannot fully preserve the rest of the config. I’ve made some
attempts to stay reasonably close to the original config but couldn’t
find an exact equivalent in a lot of cases. I don’t feel strongly
about any of the settings so happy to change them to something else.
As announced, this will be merged on Saturday to avoid too many conflicts.

I got a bit fed up by the fact that going directory by directory
didn’t really work since there are two many interdependencies in
tests (e.g., client tests depend on sandbox, sandbox tests depend on
clients, engine tests depend on DARs which depend on damlc, …).
So before attempting to continue with the per-directory process, this
is a bruteforce approach to break a lot of those cycles by porting all
dependencies of damlc which includes client bindings (for DAML Script)
and Sandbox Classic (also for DAML Script).
If this is too annoying to review let me know and I’ll try to split it
up into a few chunks.

* Cut down data-dependencies test.
This PR reduces the data-dependencies test from quadratic to linear in the number of LF versions. It does so by only testing sequential version pairs, e.g. 1.6 to 1.7, 1.7 to 1.8, 1.8 to 1.11, 1.11 to 1.dev, and 1.dev to 1.dev. These pairs covers almost all potential problem.

* Update protobuf to throw exceptions directly.

* Make choice observers mandatory when available.
This is an invariant of the DAML-LF proto.
The haskell AST allows missing choice observers for any version, because the AST represents what was written in the syntax. However, if we are targeting a new DAML-LF version (>= `featureChoiceObservers`) then `Nothing` is converted to `Just (ENil TParty)` by the haskell encoder (`EncodeV1.hs`) to satisfy the proto invariant.
On the scala side, the decoder (`DecodeV1.scala`) now insists that choice observers are present when_ the version is new. (>= `LV.Features.choiceObservers`).

(When CPP is used, Go To Definition is still pointing to the wrong place,
because the line numbers are messed up. But it's better than having a
million error messages.)
We could also remove --cpp flag in a separate PR, though that may be
considered a breaking change.

At some point in time, `daml-licenses` was supposed to list the licenses
for all of our Haskell dependencies. It's not been updated in ages, and
we now have a reliable way to get at all our dependencies.
This is arguably a bit weird since the command is `daml damlc license`,
and it lists licenses for everything (`daml license` would make more
sense), but it seems a lot better to give a correst superset than an
incorrect list.
Perhaps we can move the command to `daml license` at some point, but I'd
see that as a separate step. (That would technically be a breaking
change, but I think this one might be OK.)

This PR enforces a sequential evaluation and dependency on

in b
Into a chain of single-binding let expressions,
let x1 = e1 in
let x2 = e2 in
...
let xn = en in
b
And likewise, rewriting multi-binding let statements in a "do" block,
do
...
let x1 = e1
x2 = e2
...
xn = en
...
Into single-binding let statements,
do
...
let x1 = e1
let x2 = e2
...
let xn = en
...
This PR fixes#6788 and adds a bunch of tests.
This is a bugfix, but it may break existing code that relies on
out-of-order let bindings. The suggested fix is to simply reorder
the let bindings, placing them in order of their dependency.

* DAML-LF: Add interning for type to DAML-LF 1.dev
We add two new features to DAML-LF 1.dev:
* a per package list (or table) of `Type` messages, and
* a new case in the `Type` message which is an index into this table.
In combination, these two features can be used to allow DAML-LF
encoders to perform hash-consing of `Type` messages. We also change the
Haskell implementation of our DAML-LF encoder to do exactly that when
targetting DAML-LF 1.dev.
Doing this has a few benefits:
1. The DALFs produced by `damlc` get smaller: I've seen a case where
the size dropped from 69MB to 45MB.
2. DAML-LF decoders need to decode less data.
3. Decoded packages use less memory because identical structures are
now shared. This is particularly helpful in situations where we need
to keep the interface (or signature) of a package in memory for a
long time.
This PR mostly takes care of the Haskell implementation. However, we
need to make the Scala implementation of the decoder aware of the new
features as well since we have tests that load DAML-LF 1.dev into the
engine. A decoder and _targeted_ tests on the Scala side will follow
in a separate PR.
