Add initial GSC support for DG1 and DG2.
Create mei-gscfi auxiliary device and add
support for device created by Xe to the mei-gsc driver.
This series intended to be merged intto Xe tree,
the only patch that touches char-misc is addition
of id and alias in mei-gsc.
V2: Added heci_ to struct and APIs
heci_gsc moved under xe_device as GSC is not under GT

why are we not adding the GSC already? because dependency on the GSC
engine or something like that?

The DG1 and DG2 have only HECI-GSC routed via mei.
The pure GSC without mei is for later projects.
