In Debug mode we have assertions checking that we don't attempt OSR when
FLAG_use_osr is disabled - however app-jit snapshots are compiled with OSR
enabled and still contain countining and OSR attempting code, which causes
assertions to fail.
Refactor how getters for isolate flags are defined, consolidate all flags into
a single list.
Update test expectations and switch -c dartk configuration to use app-jit snapshot.

- When generating app-aot snapshot we are currently running Kernel isolate
in the precompiler mode, which means we can't have field guards enabled.
- DBC does not support field guards so flags must be correctly initialized.

We have tests that disable it but we train app-jit snapshot for Kernel with field guards enabled so
we need to make sure that Kernel isolate runs with correct settings matching the settings at the time
when app-jit snapshot was created.

Before it simply looked at FLAG_enable_{asserts/type_checks}.
We allow disabling or enabling type checks / asserts for newly created isolates
through Dart_IsolateFlags even when they are enabled globally through
FLAG_enable_{asserts/type_checks} flags.
This change allows isolates to use app-jit snapshots trained with type checks /
asserts disabled as long as isolate itself has type check and asserts disabled,
independent of whether FLAG_enable_{asserts/type_checks} is set globally or not.
Additionally disable type checks and asserts on Kernel isolate even if flags
FLAG_enable_{asserts/type_checks} are set.
This change allows to train Kernel app-jit snapshot once and use it both for
$ dart --dfe=...
and for
$ dart --checked --dfe=...
configurations.

The problem with these changes was that closed ports still continue to receive
messages and as a result we start using dead peer objects.
Fixing that would require more intrusive changes into message handler implementation - so instead we are reverting the changes and restoring manual PORT -> PEER mapping.

To run a script with the Dart->Kernel parser, use the -dfe option:
dart --dfe=runtime/tools/kernel-service.dart --packages=/src/d2/sdk/.packages foo.dart
The front end expects a directory named patched_sdk in the build directory (patched_sdk should be a sibling of the directory that contains the dart executable.)
Warning: using a debug build dart executable is very slow. It takes 2 minutes to run Hello World in a debug build, and about 7 seconds in a release build.
