Implement Exception Handling for classic interpreter (#3096)

This PR adds the initial support for WASM exception handling:
* Inside the classic interpreter only:
  * Initial handling of Tags
  * Initial handling of Exceptions based on W3C Exception Proposal
  * Import and Export of Exceptions and Tags
* Add `cmake -DWAMR_BUILD_EXCE_HANDLING=1/0` option to enable/disable
  the feature, and by default it is disabled
* Update the wamr-test-suites scripts to test the feature
* Additional CI/CD changes to validate the exception spec proposal cases
