Fix for event propagation in "single document" doc/view mode.

Ensure that the events still get to wxDocManager even when we are using the
single document mode in which a view can be directly associated with the
parent frame.

Closes #14314.

Disable more wxAny tests under OS X to try to find the buildbot crash.

Disabling wxVariantConversions test was not enough to fix the crash happening
in OS X PPC build slave, so disable a few more of them.

Temporarily do it for any wxOSX build, the run-time check for buildbot will be
restored later when I finally manage to find the problematic test(s?).

Test for NULL associated frame in doc/view event handling code.

A view might not have any associated frame at all (this is probably a bad idea
but we don't seem to explicitly forbid this).

This should have been part of r73943, see #14314.
