xfs: add debug knobs to control btree bulk load slack factors
Add some debug knobs so that we can control the leaf and node block
slack when rebuilding btrees.
For developers, it might be useful to construct btrees of various
heights by crafting a filesystem with a certain number of records and
then using repair+knobs to rebuild the index with a certain shape.
Practically speaking, you'd only ever do that for extreme stress
testing of the runtime code or the btree generator.
