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.

bcachefs: Invalidate buckets when writing to alloc btree

make free_inc much smaller, which means a lot fewer buckets stranded on
