drm/xe/xe3lpm: Add new "instance0" steering table

MCR steering on Xe3 media IP is almost the same as it was on Xe2, except
for one new range (0x38D0D0 - 0x38D0FF) which has changed to an MCR
"MEDIAINF" range on Xe3.  Since we can always steer to grpid /
instanceid 0 for MEDIAINF ranges, define a new "INSTANCE0" steering
table for Xe3 media.  Xe3 can continue to use the same OADDRM/GPMXMT
table as Xe2.

v2: Merge continuous entries 38D0D0 - 38F0FF
