erofs: promote to full support

JIRA: https://issues.redhat.com/browse/RHEL-78339
Upstream status: RHEL-Only

Since some of our key projects use erofs we have surveyed the code and
assessed upstream support status for the file system and this all looks
good from a support perspective. We have also updated erofs to the
upstream kernel 6.3 source.

So we are promoting erofs to full support.
Note: the user space utilities are not included in RHEL-9 (so far).
