Portals - Fix secondary PVS bug

Browse source 
Fixes a bug whereby it read from the primary PVS in the gameplay monitor, using the size from the secondary PVS. This would read out of bounds and crash.

Removed debug code to update the gameplay monitor from the preview camera - this is no longer required.

Temporarily revert to the simple PVS generation method, because I've noticed a bug in the complex version, and the simple version is safer while I fix this.
