The idea is to have a `add_mode` manager callback and enumerate adapter modes when updating display devices. Then the modes would be read from the registry and cached with the adapters and monitors, allowing us to move more things to win32u.
This MR is a preparation towards that, moving the `winex11` settings handler to display.c, and making sure we do not enumerate display modes before they have been initialized or while the list is being built.

I don't think removing these are harmless. They're there for a reason. For example, max_width and max_height refer to the physical monitor resolution. screen_width and screen_height refer to the user-emulated resolution. If I need to emulate a 2000x1000(in winecfg) on a 4000x2000(physical) monitor, removing these lines will not allow these modes to be used and only the modes listed in screen_sizes can be emulated.

While I guess it's fine to move this, I don't see the necessity to move it. Could you elaborate?

I guess we can easily keep max_width / max_height, and add a more for that, the main problem I wanted to workaround was the `NtUserGetPrimaryMonitorRect` call, which involves initializing display devices.
Though it seems to me that calling `NtUserGetPrimaryMonitorRect` returns the current monitor size, which is initialized to whatever is configured in winecfg, but may change if the modes is changed? Shouldn't we always report a mode with the winecfg resolution instead?

In https://gitlab.winehq.org/rbernon/wine/-/commit/88bbeaeadad09ddac679e402a2cc... I intend to enumerate display modes at the same time as display devices. This makes sure the desktop mode handler is set to enumerate virtual desktop modes before calling X11DRV_DisplayDevices_Init.

Right, querying from the registry seems more robust.

I see. I think it's better to put this commit before that one then.
