As suggested in #3829, in release CI, we add zip/tar.gz artifacts named
iwasm-gc-eh-{version}-{platform} for `iwasm` which supports features
garbage collection and exception handling(classic interpreter only).
Also, add a command line option to control GC heap size for `iwasm` on
the Windows platform.
- For Windows, llvm libs need to cache more directories, so use a multi-line
environment variable for paths
- Remove conditionally build directories `win32build`, just use `build` for all platform
- Add Windows wamrc and iwasm(disable lib pthread semaphore and fast jit for now)
build in release CI
Add CIs to enable the release process of a new version of WAMR,
and build and publish the binary files when a version is released,
including iwasm, wamrc, lldb, vscode-extension and wamr-ide for
Ubuntu-20.04, Ubuntu-22.04 and MacOS.
And refine the CIs to test spec cases.
