FS: Split FSA WPTs

Align our WPTs with the spec split by moving OPFS tests into a new
fs/ directory.

All Access Handle tests and most tests using a sandboxed file system
backend have been moved to fs/. file-system-access/ contains all
file picker tests and tests using a local file system backend, as
well as tests which have not yet shipped
(BaseHandle::remove() and DirHandle::move()).
