Drop AdwWindow styles, round everything instead

Alice Mikhaylenko requested to merge wip/exalm/style into main

Round corners cause rendering issues at the moment, and when those are fixed, they should be done in Adwaita globally instead, not just for AdwWindow.

Drop the outline style as well, it should be done on Adwaita level and not here.
