nir: Eliminate nir_op_f2b

Browse Source 
Builds on the work of !15121.  This gets to delete even more code
because many drivers shared a lot of code for i2b and f2b.

No shader-db or fossil-db changes on any Intel platform.

v2: Rebase on 1a35acd8d9.

v3: Update a comment in nir_opcodes_c.py. Suggested by Konstantin.

v4: Another rebase. Remove f2b stuff from Midgard.
