Restore wxObject::ms_classInfo public access

Browse Source 
This undoes accidental change of ms_classInfo from public to protected
in 95c98a0b5f (Work around -Wuggest-override for event table macros from
gcc 11, 2021-04-25).

Also add a unit test checking that using wxCLASSINFO(wxObject) compiles
and works as expected.
