AMDGPU: Handle more TargetParser queries in tablegen

Previously we had various enum switches. Start generated tables
indexed by enums. Avoid some special cases by defining the dummy
"generic" and "generic-hsa" targets as real processors.

Git commit a6d11649d8c1644328be914202fc5d92112da3d1 by Matt Arsenault on 29/07/2026 at 19:03..
AMDGPU: TableGen subarch to major subarch table

Replace the hand-written AMDGPUMajorFamilies array with a
generated lookup table. Adds a special case for the major
arches missing a concrete generic target definition (we probably
should just define those to avoid this).

AMDGPU: TableGen the subarch to processor name mapping table

name) with a generated table.

AMDGPU: Eliminate old macro driven processor name parsing

Previously the generated inc file had a series of macros for use
with StringSwitch; now just directly scan the generated name table.
