This CL changes the frontend to emit map and set constants which are
then processed by the constant reader in the VM.
This CL also introduces support for sending the const maps and sets
in messages between isolates and saving it in snapshots.
TEST=tests/language/const/map_test.dart (et al, for lookups)
TEST=tests/lib/isolate/message3_test.dart (et al, for isolate messages)
TEST=tools/test.py -c dartkp (for consts from clustered snapshot)
TEST=tools/test.py -n app_jitk-linux-debug-x64 (for consts from app
jit snapshots)
TEST=Building the SDK which uses const Maps in clustered snapshots.

This adds support lowering the encoding of top-level/static fields
with initializers as if they were marked as late fields. This ensures
that LateInitialization is thrown if final fields are written to during
initialization.

By allowing a transformation to tell if it change dthe structure of a
class we can make sure to update the class hierarchy accordingly,
making sure it's up to date for the next computeDelta call in the
incremental compiler.

We are temporarily building a smaller SDK platform to make progress building
applications against the forked sdk_nnbd sources. This is because some of the
libraries have not yet been ported and they don't compose well.
I needed to thread the status of the non-nullable experiment through the front
end entry point and into the target options, and native types.
Also includes some standardization of the flag name in DDC.

That should allow us to "implement"
6f85cb83cf again in two steps:
* first we remove the dart:profiler as a required library, but retain it in the platform
* (we wait for stuff to roll, both in flutter and in google3)
* we remove it completely (i.e. not retaining it in the platform, removing the source etc)

When we perform constant evaluation in the CFE, the async transform
runs after constant evaluation. Thus, it can no longer use const
bool.fromEnvironment("dart.vm.product") to query whether the VM is
in product mode.
Instead, it can read the product mode define directly from the
environment defines given to the CFE and generate different code
depending on the value.

The many different entrypoints to the CFE have repeatedly shown problems
with targets that do not support unevaluated constants being used
without providing an environment.
Making the targets opt-in to supporting unevaluated constants will
give the users of CFE early notice that CFE is used inconsistently
(as opposed to the backends failing when they happen to see an
UnevaluatedConstant node that they don't support).
