Xcode: Fix rebuild with multiple custom command outputs (#15116)

The Xcode generator uses Makefiles under a run-script build-phase to
drive custom commands.  Fix the generated makefiles for custom commands
with multiple outputs to list all the outputs on the left hand side of
the build rule.  This is much simpler and more reliable than the old
multiple-output-pair infrastructure.
