erofs: update compression algorithm status

The following changes are proposed in the upcoming Linux 7.0:

 - Enable LZMA support by default, as it's already in use by Fedora 42/43
   and some Android vendors for minimal filesystem sizes;

 - Promote DEFLATE and Zstandard out of EXPERIMENTAL status, given that
   they have been landed and well-tested for over a year and are
   already ready for general use.
