Wayland: Fix erratic fallback decoration behavior

Browse Source 
The handler for xdg_toplevel::configure treated the provided size as the
content area size when instead it is the size of the bounding rectangle
of the wl_surface and all its subsurfaces.

This caused the fallback decorations to try positioning themselves
outside themselves, causing feedback loops during interactive resizing.

Fixes #1991
Fixes #2115
Closes #2127
Related to #1914
