refactor(tvix/store/fs): Separate FUSE and filesystem code r/6622

In prepration for adding virtiofs support, I thought it would make sense
to split out the filesystem implementation from FUSE itself.

The `fs` module holds the tvix-store filesystem implemetation and the
`fuse` module holds the code to spawn a FUSE daemon backed by multiple
threads.
