ada: Fix glitch in handling of Atomic_Components on generic formal type

In Ada 2022 aspects Atomic_Components and Volatile_Components can be specified
for a formal array type, but then they need to be set on the base type entity.
Otherwise we get an assertion failure in debug build and wrong legality errors
in production builds.

gcc/ada/ChangeLog:

	* sem_prag.adb (Analyze_Pragma): If pragmas apply to a formal array
	type, then set the flags on the base type.
