Daco Harkes 2b5adb7231 [vm] Implement constant Maps in the VM
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.

Closes: https://github.com/dart-lang/sdk/issues/45908
