user32/tests: Add proper tests for SetActiveWindow(0).

Shows that it switches focus to some other process window and back, and
only on some older Windows versions. Win10 simply returns 0 and does
nothing.

Stop calling it elsewhere, as it makes focus go to an unpredictable
window, which may very well not be ours.
