REVIEWED: HiggDPI content scaling on changing monitors with different DPI #5335 #5356

Note that high-dpi awareness must be enabled by users and `CORE.Window.render` reports the scaled framebuffer size, while `CORE.Window.screen` reports the logical size.

`ToggleBorderlessWindow()` has also been reviewed to be consistent with scaling, if monitor physical display size is reported as 1920x1080 but there is a content scale of 1.5, then the borderless fullscreen window will be 1280x720, with the 1920x1080 framebuffer
