cmd/internal/obj/ppc64: add ISA 3.1 instructions

Use ppc64map (from x/arch) to generate ISA 3.1 support for the
assembler. A new file asm9_gtables.go is added which contains
generated code to encode ISA 3.1 instructions, a function to assist
filling out the oprange structure, a lookup table for the fixed
bits of each instructions, and a slice of string name. Generated
functions are shared if their bitwise encoding match, and the
translation from an obj.Prog structure matches.

The generated file is entirely self-contained, and does not require
regenerating any other files for changes within it. If opcodes in
a.out.go are reordered or changed, anames.go must be updated in
the same way as before.

Future improvements could shrink the generated opcode table
to 32 bit entries as there is much less variation of the
encoding of the prefix word, but it is not always identical
for instructions which share a similar encoding of arguments
(e.g PLWA and PLWZ).

Updates #44549
