#606 OwlExt::TCalcEdit and TCalendarEdit always display the popup on the primary monitor

[Ognyan Chernokozhev]

The OWLExt TCalcEdit and TCalEdit controls display their popups on the primary monitor, even if the controls are displayed in a secondary monitor.

Same most likely happens with TPickEditList as well.

Quick fix for all three controls in [r7749].

Note - since all three controls use the same code to get the current monitor screen rectangle, that code should be moved in a shared place, for example in owlext.cpp, which already contains a number of similar utility functions.

See new TSystem::GetMonitorWorkArea that I added for the implementation of ConstrainPersistentExtent, as part of the new window extent persistence [feature-requests:#258].

For convenience, you can add this overload, if you want:

auto GetMonitorWorkArea(const TWindow& w) -> TRect
{ return GetMonitorWorkArea(w.GetWindowRect()); }
