This adds the experimental support of the file system compilation cache.
Notably, experimental.WithCompilationCacheDirName allows users to configure
where the compiler writes the cache into.
Versioning/validation of binary compatibility has been done via the release tag
(which will be created from the end of this month). More specifically, the cache
file starts with a header with the hardcoded wazero version.
Fixes#618
