[ VM / CLI ] Run DartDev isolate from snapshot when possible

This change tries to run from dartdev.dart.snapshot and falls back to
running from dartdev.dill if incompatible VM flags are provided.

Fixes https://github.com/dart-lang/sdk/issues/43969

Performance results:

dart test.dart (no CLI isolate): 0.167s
dart run test (from snapshot):   0.208s
dart run test (from kernel):     0.326s

TEST=pkg/dartdev/test/load_from_dill_test.dart
