Contribution description

This changes the API of xfa from

XFA(array_name, prio) type element_name = INITIALIZER;

to

XFA(type, array_name, prio) element_name = INITIALIZER;

this allows forcing natural alignment of the type, fixing failing tests
on native64.

Testing procedure

The tests from #20959 is included here. It should now pass.
