Win32: Fix rect of undecorated maximized windows

A window created maximized and undecorated would cover the whole monitor
Windows placed it on instead of just that monitor's workarea.

This commit adjusts the maximized rect to cover just the workarea,
similar to how undecorated windows that become maximized are handled
during WM_GETMINMAXINFO.

Fixes #1806
