Brad King b8b6573db8 Xcode: Use deterministic object ids for script build phases

The Xcode "new build system" only considers a script build phase up to
date if it has run before, even if outputs are newer than inputs.  Use a
deterministic object id for script build phases associated with custom
commands so that they do not need to re-run after CMake re-generates the
project.

Fixes: #21669
