drm/xe/guc: Initialize GuC ID manager sooner

The GuC submission cleanup code may depend on the GuC ID manager,
thus we can't initialize it after registering a submission cleanup
action, as reverse cleanup sequence will destroy GuC ID manager
prior to a call to guc_submit_fini().

Move GuC ID manager initialization up, right after managed mutex
initialization, to have it available during guc_submit_fini().
