vkd3d-shader/spirv: Use runtime descriptor arrays.

Runtime descriptor arrays should be used for descriptor bindings with
a variable count.

Support for SpvCapabilityRuntimeDescriptorArrayEXT is required by the
Vulkan spec as part of descriptor indexing support.

The current implementation depends on a separate array declaration for
each range because binding_base_idx is stored in the array data. This
occurs in practice because binding.count is always different. Use of
runtime arrays eliminates the count from the key, so binding_base_idx
must be separated from the array data.
