cmd/internal/obj/ppc64: fix usage of CR bit arguments

CR bits and CR fields should be treated separately. Some instructions
modify an entire CR, a CR field, or a single CR bit.

Add a new argument class for CR bits, and teach the assembler the
recognize them as names like CR0LT or CR2SO, and update the CR
bit logic instructions to use them. They will no longer accept
register field (CRn) type arguments.

Fixes #46422
