vkd3d-shader/dxil: Do not encode the offset twice for structured TGSM loads.

Currently structured TGSM loads are encoded to something like this:

    ld_structured sr12 <s:float>, sr1 <s:uint>, l(0) <s:uint>, g0[sr1 <s:uint> + 0] <s:float>

Notice how the TGSM offset, expressed by sr1, is encoded twice in
the instruction. In TPF there is no expectation of two indices
in the resource source, so let's avoid producing it for DXIL as
well. The same instruction will therefore become:

    ld_structured sr12 <s:float>, sr1 <s:uint>, l(0) <s:uint>, g0 <s:float>
