Description of Changes
Specify the shader model directly, instead of passing a feature level to our compiler wrapper.
Always use SM5.1 on DX12.
Add the ability to compile SM4.1 (currently unused).
Rationale behind Changes
DX12 doesn’t directly tie shader model support to a feature level (A FL11.0 GPU exists that supports SM6.8 and a FL12.0 that only supports 6.5).
it should be slightly easier to add support for newer shader models if so desired.
We where previously compiling SM5.0* for DX12, yet all DX12 devices support SM5.1.
*On Intel Graphics Gen9 or newer, we would already compile for SM5.1.
Our DX11 backend is capable of falling back to FL10.0 (SM4.0).
We currently don't bother checking for FL10.1 support, if we do so in future than we can compile SM4.1 shaders for it.
Suggested Testing Steps
Test DX11/DX12 Backend.
