ab05de4ce4 bcachefs: Track incompressible data 
This fixes the background_compression option: wihout some way of marking
data as incompressible, rebalance will keep rewriting incompressible
data over and over.

26609b619f bcachefs: Make bkey types globally unique 
this lets us get rid of a lot of extra switch statements - in a lot of
places we dispatch on the btree node type, and then the key type, so
this is a nice cleanup across a lot of code.

Also improve the on disk format versioning stuff.

6eac2c2e24 bcachefs: Change how replicated data is accounted 
Due to compression, the different replicas of a replicated extent don't
necessarily have to take up the same amount of space - so replicated
data sector counts shouldn't be stored divided by the number of
replicas.
