John Ericson 470640e7fe treewide: Do a number of no-op cleanups for cross and darwin
I am taking the non-invasive parts of #110914 to hopefully help out with #111988.

In particular:

 - Use `lib.makeScopeWithSplicing` to make the `darwin` package set have
   a proper `callPackage`.

 - Adjust Darwin `stdenv`'s overlays keeping things from the previous
   stage to not stick around too much.

 - Expose `binutilsNoLibc` / `darwin.binutilsNoLibc` to hopefully get us
   closer to a unified LLVM and GCC bootstrap.
