[dxbc] Only use atomic append/consume optimization in compute shaders
...
- For fragment shaders, this isn't safe since ballots include helper invocations
- For vertex shaders, if drivers don't support subgroup operations in those
stages, we don't want it to affect the performance of compute shadres.

[dxvk] Don't duplicate geometry shader system value outputs
...
Fixes #1121 . The basic idea here is that all built-ins that can be
written by the GS will be consumed as built-ins by the FS anyway,
so we do not need to keep the o# variable around.

[dxbc] Do not emit GS system values if rasterization is disabled

Fixes issue in Star Citizen, which declares a max output vertex count
of 128 in a geometry shader which emits eight components per vertex,
which becomes 12 components in DXVK due to the gl_Position builtin.
This should keep us below the magic limit of 1024 output components.
