Vyacheslav Egorov c910738825 [vm/embedder] Introduce dart_standalone_embedder_api.h
This enables other emdedders to reuse parts of the standalone embedder
implementation without depending too much on the implementations details.

As part of the change we also remove a dependency from DartUtils on
IsolateData - by removing dart:_builtin library caching. Lookup
of this library does not seem to be on hot path anymore in Kernel world.

asiva 02e47a9731 [VM] Fix for issue 32188 (cannot use pub with --preview-dart-2)
- Fix for 'unable to read .packages file' error when generating
  kernel file (script snapshot).
- Make sync-async an isolate specific flag and turn it off for
  the kernel isolate as it runs in Dart 1 mode
- Include 'reify-generic-functions' and 'sync-async' flags to the
  list of flags to check an app JIT snapshot against.

Siva Chandra 6a6103b9c1 Do not compile script to kernel if the isolate was not created from kernel.
This change, and the code introduced, is probably not going to be required
once the platform kernel file is linked into the executable.

Siva Annamalai 6656404ad6 1. Restructure code to enable reloading when a kernel dill file is specified on the command line instead of sources.
2. Read the platform dill file at startup not for every isolate creation

3. Store the memory representation of kernel program in isolate data so that it is deleted when the isolate is shutdown

Vyacheslav Egorov a5e1f89583 VM: Fix an app-jit related shutdown race.
IsolateData contains AppSnapshot which might own some HeapPage-s, so we can't
destroy IsolateData in the Dart_IsolateShutdownCallback, because some thread
running in the isolate (e.g. background compiler) might still touch
thoses pages or objects they host.

We need to delay destruction of AppSnapshot until after the isolate shutdown.

Current API does not allow that, so we introduce a new isolate lifecycle
callback - Dart_IsolateCleanupCallback, which is invoked at the end of the
isolote lifecycle when things like background compiler have been stopped
and no Dart code is supposed to run.
