drm/amd/display: Add z-state support policy for dcn35

[Why]
DML2 means that the dcn3x policy for calculating z-state support
no longer runs from validate_bandwidth.

This means we are unconditionally allowing Z8, the hardware default.

[How]
Port the policy over to DCN35, but with a few modifications:
- Don't use min_dst_y_next_start as a check for Z8/Z10 allow
- Add support for overriding the Z10 stutter period per ASIC
- Cleanup the code to make the policy assignment more clear
