internal/lsp/cache: keep a cached workspace module dir

Keep a workspace module dir around for running the go command against a
snapshot, bound to the contents of the workspace modfile.

This uses the cache's resource model to share the workspace module dir
across snapshots if it is not invalidated, and to delete it when it is
no longer in-use by a snapshot. Of course, the go command will still
only see files on the filesystem, but using this immutable model was
most consistent with the immutable workspace.

For golang/go#41836
