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.

After staring at a type mismatch between `Nested` and `Nested` this

* 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.

* haskell side

* scalafmt
* evidence security
* 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)`.

* Make stable packages dependent on supported LF versions
Note that this just introduces an API dependency, we are not yet
filtering the list of packages. For that, I’d really like to
autogenerate StablePackages.scala since I don’t want to make that

we first change the usage sites and then switch to autogenerating than
trying to do both in one go.

roundtripTestsBy and roundtripTestsPartialBy are like their
non-By versions, except they take an explicit equality predicate
instead of relying on the Eq instance. This allows the source

* Define encoder/decoder for type synonyms
This works by saturating the RHS of the declaration with artificial
variable names and adding the corresponding parameters on the LHS
In the case of Nat type synonyms, the Proxy-like
DA.Internal.NatSyn.NatSyn type is used to wrap the value into
something of kind star.

* Typecheck nested LF type applications more efficiently
This improves performance typechecking in the Scala LF typechecker by
matching on nested foralls & type applications which allows us to
check them with only a single substitution as opposed to the previous
state of doing one for each type application.
This is about a 25% improvement on typechecking performance of
GHC.Classes from 200ms to 150ms.

Since we switch to scala 2.13, ImmArray companion object extends
`Factory`. Hence:
- the `apply` methods of `ImmArray` override the one from `Factory`
- we can use the notation `.to(ImmArray)` to convert an `Iterable` to
`ImmArray`
This PR drops those `apply` ImmArray. Conversion from Iterable to
`ImmArray` should use the `.to(ImmArray)`.

Test that Daml ledger export script handles DALF packages in LF version
1.6. These packages don't contain metadata, meanint `--package` flags

Daml script.

* Expose unconstrained Daml script commands
This will be used in Daml ledger exports of contracts defined in Daml LF
versions before 1.8. These versions did not include typeclass instances,
meaning that instances such as HasTemplateTypeRep need to be recreated
in the export Script. Not all instances required in the `Template t`
constraint can be recreated at the use-site. E.g. `HasSignatory`. By
avoiding these kinds of constraints it is possible to handle these cases
in Daml ledger exports anyway.

* Expose set of stable-packages package-ids

without metadata or not.
changelog_begin
changelog_end
* Handle package dependencies without metadata in Daml export
This addresses the immediate issue reported in
https://github.com/digital-asset/daml/issues/10435.
DALF before LF version 1.8 don't contain metadata such as the package
name and version. However, Daml ledger export assumed that metadata was
available to generate `--package` flags for data-dependencies.
This change generates `--package=<hash>` flags for such dependencies on
packages that don't have metadata available.
This change requires additional care when checking if a package is a
stable-package. As the package name is not available without metadata we
cannot just check against names such as `daml-stdlib`. Instead this
change uses the list of stable-package package-ids exposed by
`com.daml.lf.language.StablePackages.Ids`, which was introduced in
0da814d250 (diff-208c6948c7c7f2b582faa8e4792bfe78b231188881947ad0cdd5046e0b9a40e7)
Note that this does not fully resolve#10435. Building a generated Daml
ledger export script will fail on missing instances of standard classes
such as `HasTemplate` because packages prior to LF version 1.8 don't
contain type-class instances. This will be addressed in a separate PR.
