drm/xe/oa/uapi: Add/remove OA config perf ops
Introduce add/remove config perf ops for OA. OA configurations consist of a
set of event/counter select register address/value pairs. The add_config
perf op validates and stores such configurations and also exposes them in
the metrics sysfs. These configurations will be programmed to OA unit HW
when an OA stream using a configuration is opened. The OA stream can also
switch to other stored configurations.
v2: Start config id's from 1 and other minor review comments (Umesh)
v3: Add 32 bit build
v4: Add kernel doc for non-static functions (Michal)
