Fix XSendEvent crash & bootsplash.

Browse source 
Fixes a crash due to an Xlib error, as well as ensures that Godot
holds the correct size of the window after window modes have been
applied, before exiting the DisplayServerX11 constructor. This ensures
the bootsplash will be displayed with the correct dimensions.

Fixes #65320
