e7f23b41 - [SystemZ] Remove the `softPromoteHalfType` override (#175410)

[SystemZ] Remove the `softPromoteHalfType` override (#175410) `softPromoteHalfType` is being phased out because it is prone to miscompilations (further context at [1]). SystemZ is one of the few remaining platforms to override the default, so remove it here. This only affects SystemZ when the `soft-float` option is used.
