discard explicit SetAccessibleRelationMemberOf when members of a true VclFrame

I think the old use of "SetAccessibleRelationMemberOf" is a kind of workaround
to show that those widgets are logically all children of a pseudo-frame in the
a11y view. Now that they are truly children of a real frame I think we don't
need them anymore.

If it turns out that being implicit children of a frame isn't sufficient for
a11y, then hopefully we don't need to manually insert them everywhere but
instead make one centralized change down in vcl to automatically present
children of frame as "AccessibleRelationMemberOf"s.

RID_SVXQBX_DELETE_HEADFOOT: This one is still in use, so I added it back
