We've implemented "Gloss" incorrectly #3045

We've confused "Tip" and "Gloss" in Mir. We handle them identically, but in the spec there are are a couple of significant differences:

Placement: Gloss is positioned relative to the parent and not bound by the display geometry, Tip is positioned relative to a region on the parent is bound by display geometry; and,
Input: Gloss gets pointer events while the parent has focus, Tip gets no input

We've implemented both as "Tip", but we only ever set mir_window_type_gloss (mostly for things that are clearly "Tip").

I've proposed #3044 to fix labelling of "Tips", but we need to fix the implementation of "Gloss"
