Will be useful for making plasma widgets not move about
on multi monitor. QtWayland already supports it

Summary:
Done primarily for XWayland which for legacy reasons doesn't assume the
logical size of a display is pixelSize / outputScale. Meaning xwayland
windows that position themselves are wrong in a scaled environment.
It also allows the possibility for us to support fractional scaling
whilst keeping wl_output::scale as an integer.
The protocol is a bit odd as it operates via the FooManager + Foo
pattern rather than using globals like Output so I've wrapped it so it
behaves more like globals.
