drm/xe/huc: Prepare for 2-step HuC authentication
Starting on MTL, the HuC is authenticated twice, once via GuC (same as
with older integrated platforms) and once via GSC; the first
authentication allows the HuC to be used for clear-media workloads,
while the second one unlocks support for protected content.
Ahead of adding the authentication flow via GSC, this patch adds support
for differentiating the 2 auth steps and checking if they're complete.
