  [NewPM] Add missing LTO ArgPromotion pass

This is a followup to D96780 to add one more pass missing from the
NewPM LTO pipeline. The missing ArgPromotion run is inserted at
the same position as in the LegacyPM, resolving the already
present FIXME:
https://github.com/llvm/llvm-project/blob/16086d47c0d0cd08ffae8e69a69c88653e654d01/llvm/lib/Transforms/IPO/PassManagerBuilder.cpp#L1096-L1098

The compile-time impact is minimal with ~0.1% geomean regression
on CTMark.
