  [SPIRV] Add write to image buffer for shaders. (#115927)

This commit adds an intrinsic that will write to an image buffer. We
chose to match the name of the DXIL intrinsic for simplicity in clang.

We cannot reuse the existing openCL write_image function because that is
not a reserved name in HLSL. There is not much common code to factor
out.
