[API CHANGE] Drop css::accessibility::XAccessibleStateSet

which is internal API, unused (as far as I can tell) by external
users.
This state is purely a bitset
(as implemented by utl::AccessibleStateSetHelper)
so we can just return it as a 64-bit value.

This shaves significant time off the performance profiles
of code that loads very complex shapes, because this state
is frequently used, and we no longer need to allocate a return
value on the heap for every call.
