Fix static build using extended RTTI

Fix declaration of 'o' hides previous local declaration warnings.

Change two wxCONSTRUCTOR_5 definitions using wxBitmapBundle instead of
wxBitmap (this does not give build errors).

wxGenericCalendarCtrl is missing all XTI implementations, so just use
RTTI. And fix building the xti sample.

Note the shared build still fails due to WXDLLIMPEXP related issues.

Closes #22300.

Closes #22301.
