Add _make_aab target

Add target triggering AAB creation. Since the _make_aab target is
not added to the ALL set, we may avoid dependency check for it and
admit that the target is "always out of date".

[ChangeLog][Android][Platform Specific Changes] Add the extra
_make_aab targets for each executable target, that can be used
to generate android app bundles. Also add aab metatarget to build
all _make_aab targets that are created in the project.

Pick-to: 6.2
Fixes: QTBUG-96710
