[zoom bubble] Handle entering/leaving/being in fullscreen on GTK.

This patch should:
- hide the zoom bubble when toggling fullscreen
- show a bubble without an arrow while in fullscreen

This patch also:
- changes ArrowLocationGtk to FrameStyle as it's a more appropriate name
- renames all of the arrow locations to the equivalent frame styles
- adds FIXED_TOP_LEFT, FIXED_TOP_RIGHT to the available frame styles
- automatically flips bubbles in RTL to avoid making callers do this
- fixes about ~3 callers that weren't flipping
