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.

A descriptor declaration matching a range of size 1 at the end of an array binding will be emitted as a scalar variable at offset 0 in the array, which is incorrect.
