Update spec test to latest commit (#3293)

- Update spec test cases to commit bc76fd79cfe61033d7f4ad4a7e8fc4f996dc5ba8 on Apr. 3
- Update wabt binary to 1.0.34 to support newer spec cases
- Add comparison between table declared elem type and table elem segment value type
- Add a function to decide whether to execute test cases in a running mode
- Keep using interpreter in GC spec because wat2wasm in wabt can't compile if.wast w/o errors
- Re-factoring threads spec test case processing
- Since wabt 1.0.34 release isn't compatible with ubuntu 20.04, compile it from source code
- Disable CI to run aot multi-module temporarily, and will enable it in another PR
