Add the CreatePopupWindow function to allow the creation of child tooltip and menu popup windows. Popup windows must be created as either a tooltip or popup menu and cannot be minimized, maximized, made fullscreen, or grab the mouse.
Child popup windows are tracked and will be recursively hidden, shown, or destroyed in tandem with the parent window.
If we don't do this, the view will be blanked even if another context is current and rendering from that context won't be visible.
Fixes https://github.com/libsdl-org/SDL/issues/4986
Also explicitly reset fullscreen mode when destroying a window, eliminating the need for doing that in SDL_HideWindow(), as that's already taken care of in SDL_OnWindowHidden() normally.
Passing True for owner_events in the XGrabPointer call makes all
XI_RawMotion events appear in the queue twice, with the only difference
between them being the value of XGenericEventCookie::cookie. These have
always been filtered out by a check in the XI_RawMotion handler,
however with a mouse that polls at more than 1 kHz frequency, there
also exist legitimate events that appear indistinguishable from these
duplicated events. These must not be filtered out, otherwise the
pointer may move at an inconsistent speed, appearing like a bad pointer
acceleration implementation.
Change owner_events to False in the XGrabPointer and remove the
duplicate event detection code to fix this.

Setting the cursor clip area to a single pixel prevents the relative mouse motion remote desktop warping from working, so the mouse is never recentered.
Track the current window display ID locally so as not to depend on specific behavior of the video layer, which may change the value at times when it isn't expected.

When moving a window programmatically, the move event will be deduplicated due to the window x and y coordinates already being updated, so the window's current display ID needs to be explicitly updated.
Update the target display ID and use SDL_UpdateFullscreenMode() when moving a fullscreen window to handle the case where the target display has an existing fullscreen window.
