drm/xe: Add device flag to indicate standalone MERT

Browse source

The MERT subsystem manages memory accesses between host and device. On
the Crescent Island platform, it requires direct management by the
driver.

Introduce a device flag and corresponding helpers to identify platforms
with standalone MERT, enabling proper initialization and handling.
