[PATCH 1/1] win32u: virtual desktop for explorer.exe support different resolutions

[Marvin]

Hi,

It looks like your patch introduced the new failures shown below.
Please investigate and fix them before resubmitting your patch.
If they are not new, fixing them anyway would help a lot. Otherwise
please ask for the known failures list to be updated.

The tests also ran into some preexisting test failures. If you know how
to fix them that would be helpful. See the TestBot job for the details:

The full results can be found at:

[Fan WenJie (＠fanwenjie)]

It is a regression bug! for example, Running
wine explorer.exe /desktop=test,800x600
It can create a 800x600 virtual desktop window on wine-9.4, but it create a fullscreen window with resolution same as host desktop currently.

[Fan WenJie (＠fanwenjie)]

virtual_monitor is not enable, so I enanle it
