This reverts commit
5489033fa8568ecacafe32ceab36f89f2e14f3dc.
The problem I was trying to address is that we were programming the
3DSTATE_PS::PositionXYOffsetSelect bit differently with GPL (CENTROID)
than without (NONE).
I failed to understand that this bit also impacts the thread payload
layout. GPL fragment shaders don't know ahead of time if pos_offset is
going to be used. It'll be choosen at runtime base on push constant
bits. So we need to program this bit different just to have a payload
matching the compiled shader code.
This fixes the freedoom replay with GPL FS shader in SIMD32.
