81fb1cfdad dzn: Prepare support for pipeline variants
Some D3D12 states can't be updated dynamically and require the creation
of a new pipeline state. In order to support setting those dynamically
we will have to support creating pipeline variants at draw time.

59a6ddd85c dzn: Implement GetDescriptorSetLayoutSupport()
The 2048 descriptors limit comes from the maximum number of samplers
per heap, but the limit for other descriptors is actually much bigger.
Let's implement GetDescriptorSetLayoutSupport() to reflect that.

If Value is positive with a magnitude too large to represent as a 16-bit

77c81357f4 dzn: Fix vertex input handling
Vertex shaders are allowed to define input variables pointing to the
same location but a different, or even variables that overlap other
variables, as long as only one of them is used in a shader invocation.

One way to support that case would be to merge overlapping variables,
but we can also declare one input element per variable, and make those
point to the same input slot/offset. The only limitation with the
second approach is the maximum number of VS input registers, meaning
that only (32 - num_sysvals) input variables can be defined.

d3e321c853 microsoft/compiler: Make input_mappings immune to driver_location holes
Right now, nir_to_dxil() assumes driver_location on inputs will be
contiguous, which is true for GL, and also true for Vulkan shaders
with the current implementation. But we are trying to delegate
the varying linking step to Dozen, and that means the driver will
assign the driver_location field.

For everything except vertex shaders this works fine, because we
are in control of the ID we assign to each variable, and can make
sure no holes exists in this assignment, but vertex inputs expect
the index value (which is directly extracted from the
driver_location field) to match the input index defined at pipeline
creation time. The compiler has a hack to treat Vulkan differently
and extract the index from the var->data.location field instead,
but that's a bit confusing.

Moreover, the input_mappings[] array is already indexed with
the var->data.driver_location field in the input load emission
path, so it makes sense to index it with the same field when
emitting signatures.
