Avoid reflective access to mirrors creating invalid reflectees. Change type checks in embedding API functions to return UnhandledExceptionErrors instead of APIErrors so they are catchable by Dart. Fixes invocation_fuzz_test. Bug: https://github.com/dart-lang/sdk/issues/15274 Bug: https://github.com/dart-lang/sdk/issues/23869 Bug: https://github.com/dart-lang/sdk/issues/37680 Change-Id: Ife3e3cb894c59620b0318e4e08947a3d1d45bab9 Reviewed-on: https://dart-review.googlesource.com/c/sdk/+/110620 Commit-Queue: Ryan Macnak <rmacnak@google.com> Reviewed-by: Siva Annamalai <asiva@google.com>
