* 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.

* Make option based consructor the default, deprecate old constructor
* Update with review comments
* Implement a simple profiler for DAML scenarios
The profiler runs a single scenario and records timing information when
each function (and some other closures) are entered and left. The
resulting information can be visualized as a flamegraph using
[speedscope](https://www.speedscope.app/).
The profiler works by instrumenting the CEK machine at the heart of
DAML Engine. Unfortunetaly, this causes a very small overhead on
non-profiling runs too. However, in my benchmarks I could not measure
any significant impact on the overall runtime at all. More precisely,
the overhead is as follows:
Every closure now has an additional field called `label`. In
non-profiling runs this field is always set to `null`. This field needs
to be allocated, copied whenever we copy a closure and scanned during
garbage collection. Additionally, whenever we enter a closure, we check
this field and whenever it is _not_ `null`, i.e. never during
non-profiling runs, we record an "open event" and set up a hook for the
corresponding "close event". Thus, the additional cost during
non-profiling runs are a single pointer comparison and a jump beyond
the "then branch".
Since this is still very much in active development, there are no
documentation, other than an entry in a README, and no tests yet. They
will come before we promote this. However, the UX will look very
different then since we already have plans to significantly change it.

- Remove `isFinal`. A client just uses `run()`.
- Remove `toSValue`. The value in available in `SResultFinalValue(v: SValue)`.

* 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.

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.

Previously parts of the initialization, in particular, the code for
finding the filter and the heartbeat were part of the Runner. This led
to an akward API and didn’t really make any sense.
Now all of this code is part of a pure `Trigger.fromIdentifier`
method and the runner only takes care of actually running the
ledger. This could also be useful for the trigger service where we
might want to synchronously call `getIdentifier` so users get some
indication if there request even points to a valid trigger
directly. However, this is not tackled by this PR.

Previously the runner class was in a weird state where it was specific
to a DAR but not to an individual trigger. This meant that you had to
pass around a fair bit of state which got a bit awkward. This PR
addresses this by making the trigger class specific to the trigger.
It also now accepts `CompiledPackages` instead of a DAR which should
make it easier in the trigger service to support dynamic package
uploads.
changelog_begin
changelog_end
Previously we assumed that the module name was globally unique in the
DAR which is definitely not guaranteed. Now we instead detect the
package id of the trigger library based on the type of the trigger we
are running which doesn’t fall apart if there are multiple versions of
the trigger library.
I’ve also removed the check for the package id of the trigger library
since I’d like the trigger runner to be backwarts compatible from now on (we
didn’t break that in a while).
This is slightly ugly since the Runner class is currently not specific
to a single trigger but only the individual methods are aware of the
specific trigger identifier. I’ll refactor this in a separate PR.

This should provide a better migration path for people that still rely

This still contains the main class so you can use it like you would
use the fat jar but publishing fat jars to maven central is apparently
bad practise and some peple have asked for the library.

release script to avoid it complaining about the scenario proto
library not being published to Maven even though it is included in the
transitive deps.
* Spin off TokenHolder into a new library
Avoids having weird dependencies between different packages, makes TokenHolder available on Maven
* Fix auth-utils path
* language: suffix all dalfs dependencies in a dar with the pkgid.
