* Run scenarios in off-ledger machine
This PR builds on the previous PR that split scenario execution in two
different speedy machines and now actually makes the machine that runs
scenarios run in off-ledger mode just like we handle Daml Script.
This required a bunch of refactoring to make it nice so apologies for
the slightly large PR. Hopefully it’s still relatively easy to follow
and luckily it deletes more code than it adds.

It makes no sense to pass NotVisible to Speedy especially since that
is not how visibility is handled for the Engine. Also it lets us
delete code and I like deleted code.

* Split scenario & ledger execution
This PR by no means aims to solve everything we can do here. It is
rather the minimal change that I could get to work that provides us
with one Speedy machine for scenario execution (which is still an
on-ledger machine to avoid having to change the callsites to much in
this PR) and one speedy machine per submission.
There is tons of cleanup we can do afterwards but this should
hopefully set the right foundations.

* Check visibility for by-key operation of local contracts
fixes#9454
I tried out two approaches for this:
1. The one here where we add a new callback. This has the advantage
that the engine remains oblivious to visibility checks. They are all
done outside and the engine doesn’t even know about the reading
parties.
2. Make the engine aware of the reading parties. A start of that is in
#9458.
Both work in principle but I ended up going for 1 in the end. Doing
half of the visibility checks outside the engine and half inside just
seems worse than the current state.

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.

* Port damlc dependencies to Scala 2.13
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.

This does not yet relax any restrictions on command submissions. Those

nice and useful even if we do not need the guarantees.
2. it https://github.com/digital-asset/daml/pull/6542 which required
some changes since the constructors changed. If you want to review
those changes in detail (they are pretty straightforward so not too
important), it’s probably easiest to check out this PR and run

* ANF transformation in Speedy.
The idea behind this PR is to transform speedy expressions into a simpler form where all non-atomic sub-expressions are made explicit by the introduction of let-forms. In particular, for the function-application form. These simpler forms allow the execution engine to take advantage of the atomic assumption, and often removes many additional execution steps. In particular the pushing of continuations to allow execution to continue after a compound expression has been reduced to a value.

At the moment, JMH seems happy to just swallow exceptions and consider
the benchmark done, which makes it produce inaccurate speed results and
lets errors slip through to master. This makes unexpected errors in the
benchmark a hard stop.
This is not a complete solution: ideally there would be a way to just
tell jmh to abort on uncaught exceptions. However, I don't seem to be
able to find any relevant documentation on how to do that.

divulged to. Given that only stakeholders can do lookups it makes much
more sense to display them consistently which is what this PR

that does the right thing. I’ve also added some comments and an extra

The aim of the `CollectAuthority` benchmark is to track performance improvements made to the
DAML compiler & the speedy interpreter. Unfortunately the benchmark was spending at least
20% of the time being benchmarked outside of the speedy machine execution code, and
instead interacting with the ledger. We would like to minimize this as much as possible.
The solution is to cache the responses from the ledger made during the setup() run, and
replay them during the benchmark `run()`s. To perform the caching, we no longer make use
of the scenario-interpreter, but instead have our own simplified runner, specialized for
this benchmark, and managing the cache.
using the cache speeds up the benchmark by a factor of about x1.25 (Which is the origin of
the claim above about 20% outside of speedy execution).

Because of how we run perf benchmark on CI -- by running the benchmark for now vs. some
fixed time in the past -- it ought to be fine to change the benchmark like this, although
we might need some help from Gary!
As well as improving the focus of this benchmark going forwards, we should also gain a
retrospective improvement on the speedup work already committed, since they will no longer

Adapt code so the selection is made by the original caller:

Currently, all callers pass `FullStackTrace` (the existing behaviour), except for the
exploration dev-code: `daml-lf/interpreter/perf/src/main/scala/com/daml/lf/explore`.
The idea is that once this control is in place, we can discuss if we can change how we
might expose it to the user, and/or perhaps change the default behaviour to have
`stacktracing` disabled.

* remove while loop which executes just once
* avoid unnecessary mutation when running speedy
Remove the `Ctrl` trait and separate `Machine.ctrl: Ctrl` into `Machine.ctrl: SExpr` and `Machine.returnValue: SValue` instead. This allows for avoiding dynamic dispatch on `ctrl` and instead allows for checking a pointer for `null` to decide if we have an expression that needs further break-down or a return value ready to be passed to the next continuation.
To make this check really only a pointer comparison we also needed to remove the abomination of "fully applied partially applied primitives". In order to achieve this, we check whether a PAP will be fully applied afterward when applying the last argument.

Speedy: run() dont step()
- Running the Speedy machine with `run()` instead of `step()`
- Remove: `SResultContinue`
- Add: `SResultFinalValue(_)`
We change the top level control of Speedy: from machine.step() to machine.run, with the control of stepping while the machine returns SResultContinue moved into speedy itself. (And so SResultContinue is removed in favour of SResultFinalValue.) The main advantage of this approach is that the tight while loop can be moved inside the exception handler, rather than having to wrap the handler every step.

Disables support for non-default ledger feature flags, as they
are meaningless since ledger server logic does not respect the flags.
Instead of large refactoring to add support for the old flag settings,
it is best to disallow the deprecated flags, and later on phase out the
flags completely.
Re-enables test_divulgence_of_token in sandbox semantic tests.
Fixes#157.
* purge LedgerFlags entirely...
...since we only support one version of them anyway, and clearing them
* updated release notes
