Rollup merge of rust-lang#127779 - momvart:should_codegen_hook, r=cjgillot

Add a hook for `should_codegen_locally`

This PR lifts the module-local function `should_codegen_locally` to `TyCtxt` as a hook.
In addition to monomorphization, this function is used for checking the dependency of `compiler_builtins` on other libraries. Moving this function to the hooks also makes overriding it possible for the tools that use the rustc interface.
