[dxbc] Use SSBOs for dynamically indexed constant buffers if needed 
SSBOs are tightly bound-checked on all Nvidia GPUs, so this allows for
a more accurate workaround for games relying on OOB access behaviour.

[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.

[dxbc] Enable early discard on RADV/ACO 
Still can't enable on LLVM due to GPU hangs. The way we detect it
may have to change in the future, but for now, this should do.

[dxbc] Disable atomic counter optimization on old RADV versions 
Breaks TressFX in Tomb Raider 2013 for some reason, whereas this works
fine on 19.1 with both LLVM 8.0 and 9.0-git.

[dxbc] Repurpose useRawSsbo option 
Basically, abuse the minSsboAlignment property to convince the
compiler to always/never emit raw SSBOs for raw and structured
buffers, and use the actual device limit by default.

[dxbc] Add option to use subgroup ops for atomic counter operations 
This can greatly reduce the number of atomic operations when using
append/consume buffers.

[dxbc] Disable Constant Buffer Range Check on AMD 
The hardware already behaves as intended, no need to waste GPÜ cycles.

[dxbc] Only emit depth clamp in fragment shader if necessary 
We don't need this if the depth clip extension is supported
by the driver.

[dxbc] Add option to enable strict sm4-compliat division 
SM4 is defined to return the first source operand if the divisor is zero.
Windows drivers don't do this by default, so we shouldn't do it either.

[dxbc] Add useRawSsbo option 
ENabled when we can replace texel buffers for raw and structured
buffers with raw SSBOs.

[dxbc] Check for RADV/Nvidia drivers explicitly using the new function 
This way, only RADV gets locked out of using early discard whereas
AMDVLK and -PRO are able to use it.

[dxbc] Refactor DxbcOptions 
A bit mask isn't good enough going forward, and we also don't
need application-specific options for now.

[dxvk] Add extended device feature structure 
This allows the client API to query and enable extended

like the extende feature queries.
