  [SPIRV] Do not emit @llvm.compiler.used (#162678)

`@llvm.compiler.used` holds a series of global values and prevents the compiler from optimizing them out.

However, the symbols in the variable can be optimized after compilation
as usual by a linker (notice that `@llvm.used` instead doesn't allow for
the linker to optimize-out the global variables referenced in it).

This was already done for `@llvm.global.annotations`.
