Ada: Fix internal error on ill-formed Reduce attribute in Ada 2022

This is an internal error on the new Reduce attribute of Ada 2022 when the
programmer swaps its arguments(!)  The change makes it so that the compiler
gives an error message instead.

PR ada/117517
* sem_attr.adb (Resolve_Attribute) <Attribute_Reduce>: Try to
resolve the reducer first.  Fix casing of error message.
