Refactor CI rules: merge ubuntu/macos/android, enable spec test (#777)

Refactor CI rules:
- merge ubuntu/macos/android into one job file
- add job file to test spec cases
- add compilation for lazy jit, debug interpreter and debug aot
- add compilation for performance profile, dump call stack and mini-loader
- re-org llvm build script to build lldb
