[HLSL][SPIR-V] Implement vk::ext_builtin_input attribute (#138530)
This variable attribute is used in HLSL to add Vulkan specific builtins
in a shader.
The attribute is documented here:
https://github.com/microsoft/hlsl-specs/blob/17727e88fd1cb09013cb3a144110826af05f4dd5/proposals/0011-inline-spirv.md
Those variable, even if marked as `static` are externally initialized by
the pipeline/driver/GPU. This is handled by moving them to a specific
address space `hlsl_input`, also added by this commit.
The design for input variables in Clang can be found here:
https://github.com/llvm/wg-hlsl/blob/355771361ef69259fef39a65caef8bff9cb4046d/proposals/0019-spirv-input-builtin.md
