Giovanni Mascellani 5f2f126b70 include: Include stddef.h in vkd3d_shader.h.
Type size_t is used in the file without importing any header which
defines it. This only works when the translation unit includes one of
the appropriate headers anyway or when the appropriate header is included
internally by other standard C headers; none of those strategies should
be relied upon.

* source code or byte code.
*
* This version of vkd3d-shader supports the following transformations:
* - VKD3D_SHADER_SOURCE_DXBC_TPF to VKD3D_SHADER_TARGET_SPIRV_BINARY
* - VKD3D_SHADER_SOURCE_DXBC_TPF to VKD3D_SHADER_TARGET_SPIRV_TEXT
* (if vkd3d was compiled with SPIRV-Tools)
* - VKD3D_SHADER_SOURCE_DXBC_TPF to VKD3D_SHADER_TARGET_D3D_ASM
* - VKD3D_SHADER_SOURCE_D3D_BYTECODE to VKD3D_SHADER_TARGET_SPIRV_BINARY
* - VKD3D_SHADER_SOURCE_D3D_BYTECODE to VKD3D_SHADER_TARGET_SPIRV_TEXT
