Code Review

This pull request updates AppleTestUtils by removing several obsolete Dart VM and Isolate snapshot symbols from the requiredSymbols list. The review feedback suggests adding the merged _kDartSnapshotInstructions symbol to this list to ensure integration tests verify its presence in generated Apple binaries.

high

With the merging of VM and Isolate snapshots in the Dart SDK, the instructions symbols _kDartIsolateSnapshotInstructions and _kDartVmSnapshotInstructions are merged into _kDartSnapshotInstructions.

We should add _kDartSnapshotInstructions to the requiredSymbols list to ensure that the integration tests verify the presence of the merged instructions symbol in the generated Apple binaries.
