Continues the work started in https://github.com/digital-asset/daml/pull/12543
These libraries were only needed to transition from Scala 2.12 to 2.13
and are no longer useful as all the necessary items are now available
in Scala 2.13.
changelog_begin
changelog_end
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.

Following #12338 which merges the two implementations of the
structural record projection introduced by #7740, this PR merges the two
implementations of the structural record introduced by #7742.
However, this PR does not try to cache the field index as it is done
1- unlike what it is suggested by commit message of #7742, the update
has a linear complexity anyway, as it has to copy the whole struct.
2- the compiler does not produce any structural record updates
As result the PR is basically a revert of #7742.
CHANGELOG_BEGIN
CHANGELOG_END
Currently we have two implementations for the projection of structural
record.
1- The first implementation takes as parameter the index of the
projected field and is therefore constant. This implementations is
used when the type checking is enable, as the index cannot be directly
inferred from the AST and must hence be filled in by the DAML-LF type
checker.
2- The second implementation takes as parameter the name of the
projected field and is therefore logarithmic as the field must be
lookup by binary search at each call. This version is used when the
type checking is disable as the index cannot be inferred without type
inference.
In this PR, we modify the second implementation so it cache the index
at the first call, hence avoiding the recomputation during further
calls. In this way we reach an amortized constant complexity. The
first implementation is decommissioned in benefit of the second one.
The advantages of this approach are:
- We have a unique implementation of the projection, so the behavior
of a program is the same whenever the type checking is on or off.
- The AST for structural projection is immutable.
Benchmarks show no performance differences when the type checking is on.
Based on an idea by @sofiafaro-da.

* 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.

* fix TypingSpec test
* 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.)

* 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)`.
