Window management improvements.

[macOS] Fix transient windows not working in the full-screen mode.
[macOS] Fix moving transient windows to the other screen than parent window.
[macOS] Fix popup menu switch on hover.
[macOS] Use content origin rect for windows position (to ensure `DS.mouse_get_position` is equal to `DS.window_get_position` + mouse position from the input events).
[macOS] Fix incorrect input coordinates, when external display with different scaling in connected/disconnected.
[macOS/Windows] Fix moving fullscreen windows between the screens.
Add auto refocusing of the parent window, when the focused transient window is closed.
Remove redundant `DS.mouse_get_absolute_position` function (returns mouse position in the screen coordinates, same as `DS.mouse_get_position`).
