drm/amdkfd: gfx12 context save/restore trap handler fixes
Fix LDS size interpretation: 512 bytes (>= gfx12) vs 256 (< gfx12).
Ensure STATE_PRIV.BARRIER_COMPLETE cannot change after reading or
before writing. Other waves in the threadgroup may cause this field
to assert if they complete the barrier.
Do not overwrite EXCP_FLAG_PRIV.{SAVE_CONTEXT,HOST_TRAP} when
restoring this register. Both of these fields can assert while the
wavefront is running the trap handler.
