bcachefs: New and improved __bch2_bkey_unpack_key()

This implements a new and improved __bch2_bkey_unpack_key() as suggested
by Eric Biggers; we use a postprocessing step to compute byte indexes
and masks, and then fetch each packed field with a simple fetch and
mask, which are now able to run in parallel.

This should provide roughly similar performance to the dynamically
generated bkey unpack functions dropped by the previous patch.
