osd: Add extent_to_shard_extent interface to PGBackend.

This allows a backend to expose how an object offset/length translates to
an offset/length on a particular shard.

For Replica, this is trivial.

For EC, this means looking up the start and end offsets, then translating
this to shard address space.
