Vadim Zeitlin e18a74e240 Take disabled windows into account in wxFindWindowAtPoint() in wxMSW.
Use ChildWindowFromPointEx(CWP_SKIPINVISIBLE) to ensure that we find the
disabled children (by not using CWP_SKIPDISABLED).

Add a unit test to check for the correct behaviour in all cases and document
it.

Closes #2942.
