drm/xe/oa: Enable Xe2+ PES disaggregation
Enable Xe2+ PES disaggregation (for OAG) to retrieve disaggregated metrics
when disaggregated data is needed. Userspace can select whether to receive
aggregated or disaggregated metrics via the particular OA configuration it
uses (programmed via DRM_XE_OBSERVATION_OP_ADD_CONFIG).
