Use wxCONTROL_FOCUSED control state flag when drawing native wxPG check box in the "modified state" under wxOSX.

Generally, wxCONTROL_PRESSED control flag is used when drawing native check box (wxPGEditor_CheckBox) in "modified state" but under wxOSX this flag is equivalent to wxCONTROL_CHECKED flag and hence it is necessary to indicate this state in an alternative way.

Closes #16696
