xdg-shell/positioner: Clarify flip semantics with anchor offset

Browse source 
While there is no currently known usages of setting an anchor offset on
the same axis as the 'flip' constraint action is set, it must still be
specified so compositors behave the same.

surface is constrained, the gravity is 'bottom' and the anchor is
'bottom', change the gravity to 'top' and the anchor to 'top'.
The adjusted position is calculated given the original anchor
rectangle and offset, but with the new flipped anchor and gravity
values.
If the adjusted position also ends up being constrained, the resulting
position of the flip_y adjustment will be the one before the
adjustment.
