When calling SetForegroundWindow for a window in another thread, an
internal message is posted to the thread's message queue.
If this thread then calls SetForegroundWindow before processing its
messages it will execute the corresponding set_active_window first,
but then overwrite the active window later, when processing its internal
messages.
This is not always the correct behavior and these tests help determine
what should actually be done in various situations.
This aims to check the following sequences, with A being a separate
thread that created three windows, and B being the main test thread
with some windows initially in background:
* window A0, A1, or A2 is foreground, then:
* B sets foreground to window A0
* A sets foreground to window A1
As well as these sequences where foreground is also temporarily switched
to window B0:
* window A0, A1, or A2 is foreground, then:
* B sets foreground to window B0
* B sets foreground to window A0
* B sets foreground to window B0
* A sets foreground to window A1
In addition, we also do tests with additional SetActiveWindow / SetFocus
calls to check their influence.

Another try at this. Back to message filtering, as it's a more generic
solution than last time counter.
It still needs to be able to filter these internal messages so we have
to change get_message request handler a bit. We don't provide any way
to specifically remove messages though.
v2: * Remove cross-process test and the related debugger patch, the
results are the same as cross-thread.
* Trace counted messages in the test so we can compare traces, add
more test traces too.
* Send a WM_USER message too, to validate that we shouldn't process
sent messages while filtering internal messages.
* Filter internal WM_WINE_SETACTIVEWINDOW messages using a thread
local flag and a call to peek_message.
* Add a fix for the additional focus messages received when calling
SetFocus, even if the window already has focus, fixing the last
remaining todo in the test.
