xfs: split out a btree type from the btree ops geometry flags

Two of the btree cursor flags are always used together and encode
the fundamental btree type.  There currently are two such types:

 1) an on-disk AG-rooted btree with 32-bit pointers
 2) an on-disk inode-rooted btree with 64-bit pointers

and we're about to add:

 3) an in-memory btree with 64-bit pointers

Introduce a new enum and a new type field in struct xfs_btree_geom
to encode this type directly instead of using flags and change most
code to switch on this enum.
