vc/intel/fsp/fsp20/meteorlake: Add VR config entries

This patch adds UPD entries into the FSP header file to configure VRs
(IA, GT and SA).
- `IccLimit` : VR Fast Vmode ICC Limit support
- `EnableFastVmode` : Enable/Disable VR FastVmode
- `CepEnable` : Enable/Disable CEP (Current Excursion Protection

BUG=b:286809233
TEST=Able to build google/rex.
