Ada 2022 requires that an Aggregate aspect specification shall specify a
a name for at least one of Add_Named, Add_Unnamed, or Assign_Indexed.
Enforce this rule.

gcc/ada/

	* sem_ch13.adb
	(Validate_Aspect_Aggregate): Reject illegal case where none of
	Add_Named, Add_Unnamed, and Assign_Indexed are specified.

Tested on x86_64-pc-linux-gnu, committed on master.
