Enhance GC subtyping checks (#3317)

Enhance the GC subtyping checks:
- Fix issues in the type equivalence check
- Enable the recursive type subtyping check
- Add a equivalence type flag in defined types of aot file, if there is an
  equivalence type before, just set it true and re-use the previous type
- Normalize the defined types for interpreter and AOT
- Enable spec test case type-equivalence.wast and type-subtyping.wast,
  and enable some commented cases
- Enable set WAMR_BUILD_SANITIZER from cmake variable
