Adds a new code path for NativeCallable.isolateLocal invocations. If the current thread is not entered into any isolate, but owns the target isolate, then it enters the target isolate, invokes, then exits the isolate. Fixes: https://github.com/dart-lang/sdk/issues/61623 TEST=tests/ffi/function_callbacks_isolate_ownership_test.dart Change-Id: I401f185fadf7d2a55190dafd15387e1c418c67c9 Reviewed-on: https://dart-review.googlesource.com/c/sdk/+/452380 Reviewed-by: Ryan Macnak <rmacnak@google.com> Commit-Queue: Liam Appelbe <liama@google.com>
