Since #8629, the content size isn't set until the window is shown, so we can't know the frame size.

A non-client click was being received after the click to minimize the window, which caused a call to `_parent->BringToFront();`, meaning the window got immediately restored. Ignore clicks when the window is minimized.

Fixes #8335

Previously, `_actualWindowState` was being set after the window state had finished changing, but `ExitFullScreenMode` calls `UpdateStyle` which expects `_actualWindowState` to be up-to-date, meaning that previously we ended up with an invalid size when exiting full screen mode programatically.

`Window.Position` isn't an Avalonia property so doesn't auto-update, we need to listen for `PositionChanged`.

- Add a retry to `GetWindowInfo`
- Owned windows can't go fullscreen on macOS.

This reverts commit 20ddbad.

It didn't work with owned windows, there's something else going on here.

The previous solution didn't work for owned windows. Hopefully this fixes the problem at its root: that `BringToFront` activates a window even if it's miniaturized.

MacOS sometimes seems to need a bit of time to get itself back in order after switching out of fullscreen.

Seems to cause less flaky tests; `mainWindow.Click()` clicks the main window in the middle, where the secondary window is shown, so don't go out of our way to put the secondary window in front of where we're clicking.
