Xenko window should remember monitor/window position (per project)

Release Type: official 4.0.0.1-beta2-0926
Version: official 4.0.0.1-beta2-0926

Platform(s): Windows

Describe the bug

The Xenko studio widow starts on whatever monitor the mouse happens to be when it finally creates the window, but it takes quite a long time to launch. This is really annoying, because I often do something else during the long launch time, and then it starts up on the wrong monitor -- every time.

It should (a) remember the last monitor/window position per project, like visual studio, and (b) get the current monitor the moment it is launched, instead of only when the window is created. so it'll start on the monitor where the mouse was when it was launched, not wherever it is when the user is doing something else while waiting for it to launch.

To Reproduce
Steps to reproduce the behavior:

1. launch the Xenko launcher on the primary monitor
2. click the big red "Start 4.0.0.1-beta02-0926" button (or equivalent)
3. move the mouse to a secondary monitor
4. WITNESS: when Xenko finally starts 20-60 seconds laster, it comes up on the secondary monitor, because this is where the mouse happens to be while waiting for Xenko.

Expected behavior

I expect Xenko to (a) start up on the monitor and window position it was last closed at in the project, and (b) on a new project, I expect it to start on the monitor where the mouse was when it was launched, not 20-60 seconds later when it decides to finally create the window.

Additional context

Other similar tools remember the monitor and window position per project, and start on the monitor where the mouse was the moment they are run/launched, not 20-60 seconds later.

Start by reproducing the issue through the Xenko launcher, using the large red start button and the Windows Studio startup flow described here. Done means a project reopens on its last monitor and window position, while a new project uses the launch-time monitor rather than the monitor occupied later during startup.
