Revert "ir/spirv-writer: Emit entry point declarations" 

This reverts commit 90789ea1f8.

Reason for revert: Compilation errors on MSVC and some linux machines.

Original change's description:
> ir/spirv-writer: Emit entry point declarations
>
> Emit the OpEntryPoint instruction with the pipeline stage. Interface
> variables will be done later.
>
> Emit OpExecutionMode instructions for the workgroup size and fragment
> shader origin, depending on the pipeline stage.
>
> Bug: tint:1906
