  [AMDGPU][NFC] Add CuModeOnly feature

Introduce a dedicated subtarget feature for targets that only support CU mode.
Use it instead of isGFX1250.

GFX13 can support both CU and WGP modes while still exposing GFX1250
instructions, so checking isGFX1250 is not specific enough for CU-mode-only
behavior.
