* Update LF spec for exceptions.
The changes here are:
* Removing the built-in exception types
* Changing the result in the operational semantics to include both an "exception thrown" case and a "fatal error" case.
* Cleaning up the semantics of create/exercise/etc and try/catch.
Not included in this PR is anything to do with built-in arithmetic exceptions. There's room to add it in the future (as a value of AnyException type), but I would do it in a follow-up PR.

* finish renaming Throw cases
* Update type ordering for AnyException.
The name of some builtins will be exposed as part of the Exception

Just some small changes to take into account the new ledger model transaction structure (see #9396). This PR doesn't fix all the issues with the LF spec not matching the ledger model, but it tries to avoid widening that gap.
* Removed itr, iexercise which we don't need.
* Removed the exception type and value from the rollback node.
* We're not calling rollback nodes ledger actions anymore, so separate it out.

- Fix the order of RoundingMode constructors in GHC.Types to match the LF built-in order. Try to match this order across all code and documentation, and added a test for this order.

This PR adds a hook in the compiler and the engine to allow easy prototyping of new features.
In particular by using this hook, one can add a new feature in 1.dev with modifying:
compiler
type checkers (both Haskell and Scala)
archive Protobuf
archive decoder
In addition of development speed, this also adds a bit of confidence, as the peaces enumerated above are not touched when adding the feature: The feature can be added by modifying only 1.dev Daml standard library and Speedy.
aa7991f8 shows a use case of this hook.

* Require pattern match exhaustiveness in spec.
Changes the rules for case expressions to require exhaustiveness.
This involves moving out the "well-formed case alternative" rules
to a separate judgement, and introducing a "pattern match
exhaustiveness" judgement.
The symbol ⊲ used for pattern match exhaustiveness comes from
sheaf theory and formal topology, where "A ⊲ B₁, …, Bₙ" means
"A is covered by { B₁, …, Bₙ }", indicating an exhaustive
coverage of A by possibly overlapping conditions B₁, …, Bₙ.
For example, see [this nlab page](https://ncatlab.org/nlab/show/posite).
It seemed appropriate.

* Normalize struct field order in the LF spec.
This commit changes the LF spec to ensure that struct field order is ignored whenever reasonable.
* Rename "type synonym resolution" to "type normalization", and change the rule for structs to also normalize the order of fields.
* Make the struct type "well-formed" only if the struct fields are sorted by field name. (This matches the way "well-formed" is only used for normalized types. E.g. type synonyms are not considered "well-formed" by the spec. This nomenclature should possibly be fixed in a separate PR.)
* Change the struct con expression type rule accordingly.
* Change the definition of a struct value. A struct value is now a struct expression where all the field expressions are values, and all the field names are sorted.
* Change the evaluation rule for struct expressions to also sort the fields by field name in the process.
As far as I know, this spec matches the behavior of the LF engine. I also tried to make the treatment of struct field order in the types match the treatment of struct field order in expressions (i.e. normalized structs always have sorted fields, but non-normalized structs do not).

* Evaluation order for exercise & other updates.
This adds more DAML tests and error cases for, finishing off the update
interpretation for now. I believe this is roughly the limit of what we
can test directly in DAML, and the rest is up to DAML-LF testing.
For example, there's no way to test that the contract inactivity check
in EvUpdExercInactive happens before the evaluation of the controller
expression, since there is no way to generate an 'exercise' with actors
from DAML, as far as I could tell, and 'exercise_without_actor' always
evaluates the controller before passing it off to 'exercise'.
For the same reason, the EvUpdExercBadActor check seems impossible to
trigger from DAML itself. The closest is an authorization test that
happens during submit (which I added a test for, because it is kinda
relevant to evaluation order of scenarios, even though scenario
interpretation isn't really important to the spec).
So at the very least we should add LF tests for those two cases.

In our first design draft, the maintainers of a contract key were
computed from the template payload. Now, they are computed from the
key itself. The rule `EvUpdCreateWithKeySucceed` still reflect the old
behavior but changing a single index from `t` to `v` fixes the issue.

* Freeze DAML-LF 1.8
Two minor points that I did not mention in the previous PR:
We also include the renaming of structural records to `struct` and the
renaming of `Map` to `TextMap`.
There are some minor changes around the LF encoder tests which need to
be able to emit package metadata properly so I’ve added it to the
parser. Sorry for not splitting that out.
Following the process used for the DAML-LF 1.7 release, this does not
yet include the frozen proto file.
changelog_begin
- [DAML-LF] Release DAML-LF 1.8:
* Rename structural records to ``Struct``. Note that
structural records are not exposed in DAML.
* Rename ``Map`` to ``TextMap``.
* Add type synonyms. Note that type synonyms are not serializable.
* Add package metadata, i.e., package names and versions.
Note that the default output of ``damlc`` is stil DAML-LF 1.7. You
can produce DAML-LF 1.8 by passing ``--target=1.8``.
