drm/amdkfd: Add support for more per-process flag 



Add support for more per-process flags starting with option to configure
MFMA precision for gfx 9.5

v2: Change flag name to KFD_PROC_FLAG_MFMA_HIGH_PRECISION
    Remove unused else condition
v3: Bump the KFD API version
v4: Missed SH_MEM_CONFIG__PRECISION_MODE__SHIFT define. Added it.
