drm/amd/display: Add utm_support capability flag

Browse Source 
[Why]
Expose whether the ASIC supports Universal Traffic Management so
upper layers can query the capability instead of assuming support.

[How]
Add a new bool capability field to dc_caps, defaulting to false,
and set it to true during DCN6 resource construction.
