    d3d12: Update varying creation logic to handle location_frac
    
    When multiple variables are packed into the same location, we need
    to re-construct variables that read/write the same components of that
    register so that the DXIL signature is correct. We could try to
    merge these variables, but getting the types right sounds harder than
    just preserving the multiple individual variables.

    d3d12: Link tesselation control and eval shaders
    
    GLSL puts a bunch of tessellation info in the eval shaders, because
    passthrough control shaders can exist. D3D12 puts it in the control
    (hull) shader instead. So, when specializing, copy info from domain
    to hull. For initial compiles (no domain shader), just make something
    up.
    
    D3D12 also requires the domain and hull shaders to have identical
    patch constant signatures. Use the existing infrastructure and extend
    it to also propagate patch constants. Notably, patch constant locations
    are outside of the 64-bit range value so they require a separate pass
    to avoid shifts larger than 64.

    d3d12: Enable PIPE_CAP_TGSI_TEXCOORD
    
    This is required to be able to use the necessary number of varyings,
    otherwise we hit asserts because mesa/st starts assigning varyings
    locations above 64 due to the +9 reserving these texcoords.

    microsoft/compiler: Handle clip/cull distance as an input to tess shaders
    
    In order to get the semantics right, we need to know how many of the clip/
    cull fields are designated for which purpose. In the case of a shader that
    can receive these fields as both input and output, the shader_info property
    is reserved to store the output info. We could add a dedicated input field
    to shader_info, but since it'd probably only be useful for us, just send
    it through a side channel during shader linking.

    microsoft/compiler: Primitive ID should only be added as a sysval in geometry shaders
    
    Docs say that its presence in signatures as a "shadow" element (meaning it's not
    accessed via load/store, but with a dedicated opcode) is legacy. It seems it
    wasn't carried forward when HS/DS were added in D3D11.

    microsoft/compiler: Use driver_location instead of location for inter-stage varying index in GL
    
    In the case of two vars being packed into the same register / location,
    they'll still get unique driver_location, which is what we need.
    
    This does require some tweaks to stream output handling, which also needs to
    produce the varying index.
