Components only span across a single regset, so instead of expecting the
regset as input for the offset, hlsl_type_get_component_offset() can
actually retrieve it.

Change to use uint32_t as requested.
This change ensures that we don't dump the writemask for registers that
have a scalar dimension.
For instance, for this shader:
float r;
float4 main(out float d : DEPTH) : sv_target
{
d = r;
return 0;
}
we now correctly dump
dcl_output oDepth
instead of
dcl_output oDepth.x
The assumption that sampler registers never have a swizzle is not
totally correct.
For instance, for the following shader:
Texture2D tex;
sampler sam;
float4 main() : sv_target
{
return tex.GatherGreen(sam, float2(0, 0));
}
the gather instruction is being disassembled as
gather4_indexable(texture2d) o0.xyzw, l(0.0, 0.0, 0.0, 0.0), t0.xyzw, s0
instead of
gather4_indexable(texture2d)(float,float,float,float) o0.xyzw, l(0.0, 0.0, 0.0, 0.0), t0.xyzw, s0.y
(notice the missing swizzle in the last parameter s0).
This is because the Gather instructions give the sampler register a vec4
dimension (and scalar swizzle type) to indicate the channel for the
gather operation.
The solution is using the new vkd3d_shader_register.dimension instead of
checking the swizzle type.
