Uses the private patch constant array for tess factor built-ins. Fixes two separate issues encountered in Shadow of the Tomb Raider:
- The output registers that have one component mapped to any of the TESS_FACTOR sysvals can have their other components mapped to a regular patch constant output, in which case we need to use a private io variable.
- The tess factor outputs are not necessarily dynamically indexed within shader code. Previously, this did not work correctly and lead to invalid store operations in the generated SPIR-V.
