Add Windows wamrc and iwasm build in release CI (#3857)

- 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
