Merge X11+D3D FreeLook feature into DolphinWX

This removes the redundant code and also implements this feature for OSX and Wayland.
But so it's dropped for non-wx builds...

imo DolphinWX still isn't the best place for this, but now it's in the same file as all other hotkeys. Maybe they'll be moved to InputCommon sometimes at once ...
