* 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.

* Switch from `@silent` to `@nowarn`.
This annotation is native to Scala 2.12.13+ and 2.13.2+. It replaces
most usages of `@silent`.
I had to get creative about a couple of use cases that didn't work.
Specifically:
1. Suppressing deprecation warnings works, but Scala 2.12 erroneously
complains that the `@nowarn` is unnecessary. I had to suppress
this warning too with `-Ywarn-unused:-nowarn`.
2. I can't seem to suppress the warning, "The outer reference in this
type test cannot be checked at run time." Instead, I have
refactored the code to remove the warning.
We still need to use the silencer plugin to suppress some warnings about
unused imports (because of compatibility between Scala 2.12 and 2.13),
but this means we no longer need the library, and therefore it is not a
transitive dependency that downstream consumers need to worry about.

* Port //daml-lf/interpreter to Scala 2.13

This is necessary to at least attempt an upgrade to 2.13 and
generally, I want to keep our rulesets up2date. rules-scala forces the
version of scalatest so we have to bump that at the same time.
This requires changes to basically all Scala test suites since the
import structure has changed and a bunch of things (primarily
scalacheck support) got split out.
Apologies for the giant PR, I don’t see a way to keep it smaller.

* Speedy: Reintroduce usage of muti-binding let.
This PR fixes recursion issue with `closureConvert` and `freeVars`.
The explosion of muti-binding in single binding makes the function
`closureConvert` crash with stackoverflow in some cases.
We reintroduce the usage of multi-binding let in the first pass of the
compiler. The ANF transformation pass will replace them with nested
single binding let. ANF pass do not have issue with deep expression,
as it handle them with trampoline.

* Revert ANF changes and add a testcase for evaluation order
After careful consideration, we decided that the change in evaluation
order that was accidentally introduced by the ANF changes should be
considered a breaking change or arguably even a bug and should not
land in 1.3.0.
Therefore, this PR reverts the following commits:
1. 353d0da6f7
2. a45b51042f
3. 04c7b2af7f
4. a624dd7242
5. b3aab72cee
Other PRs mostly had trivial merge conflicts that I resolved. The two
most interesting ones here are probably
1. https://github.com/digital-asset/daml/pull/6576 which was easy to
resolve and the change to return SEValue instead of SExpr is still
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
```
git diff 2cd2a8f2a8
daml-lf/interpreter/src/main/scala/com/digitalasset/daml/lf/speedy/Compiler.scala

to see the diff to the parent commit of the first commit that

the `Event#label` rendering function makes, anyway. Now, we type-check that
the labelling matches the renderer.

* 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.

As mentioned in the title, this is still very experimental and needs
more work before we want to advertise it. However, the code is in a
somewhat reasonable shape, there are tests and I think even in the
current state it is already useful. Also this PR is already getting
very large so I don’t want to hold off much longer before merging this.
It is included in the SDK but hidden from `damlc --help` and `daml
--help` until the most pressing issues are addressed (primarily around
making sure that it doesn’t just shut down if you have a type error
and better error messages in general).

This is a first step towards DAML triggers. At the moment, triggers
can consume (very simplified) create and archive events via the Ledger
API, update a state based on that and emit log mesages at each update.
All of this is likely to change significantly in the future, so I
would prefer to not focus too much on minor details for now.
As a test, I added a simple trigger that tracks active contract ids.
Add field 'usedPackages' to Transaction to record the packages
that were used during interpretation to produce said transaction.
This serves as a hint to specify what packages are required to
validate the transaction. Note that this may not be sufficient
for future implementations that e.g. compile DAML-LF to JVM
bytecode and require packages containing only type definitions
as inputs.
This hint is mainly required for ledger implementations for which the
packages are tracked similarly to contract instances, and which
require that all inputs to their transaction must be declared
beforehand.
This work is required for the participant-state key-value utilities
described in issue #410 and implemented in PR #637.
* Add buildifier targets.
The tool allows to check and format BUILD files in the repo.
To check if files are well formatted, run:
bazel run //:buildifier
To fix badly-formatted files run:

* Cleanup dade-copyright-headers formatting.
* Fix dade-copyright-headers on files with just the copyright.
* Run buildifier automatically on CI via 'fmt.sh'.
* Reformat all BUILD files with buildifier.
Excludes autogenerated Bazel files.
