Render Window as Non-Child on Win32 platform

This patch makes the "Render" window a top-level window, not a child of
the main window, which was the case in blender versions prior to 2.93.
This means it is no longer "on top", nor is the icon grouped on the
taskbar in the same way, but you can Alt-Tab between it and the main
window. This change only affects the Windows platform as the other
platforms behave this way.

See D11576 for links to negative feedback that prompts this change.
