reflog + refs-backend: move "verbose" out of the backend
Move the handling of the "verbose" flag entirely out of "refs/files-backend.c" and into "builtin/reflog.c". This allows the backend to stop knowing about the EXPIRE_REFLOGS_VERBOSE flag. The expire_reflog_ent() function shouldn't need to deal with the implementation detail of whether or not we're emitting verbose output, by doing this the --verbose output becomes backend-agnostic, so reftable will get the same output. I think the output is rather bad currently, and should e.g. be implemented with some better future mode of progress.[ch], but that's a topic for another improvement.
