drm/xe/pf: Restrict device query responses in admin-only PF mode

Browse source

When a PF is configured in admin-only mode, it is intended for management
only and must not expose workload-facing capabilities to userspace.

Limit the exposed ioctl set in admin-only PF mode to XE_DEVICE_QUERY and
XE_OBSERVATION, and suppress capability-bearing query payloads so that
the userspace cannot discover execution-related device details in this
mode.
