Previously the radio menu items could only be appended to a menu in wxMSW,
inserting them (either in an existing radio group or to start a new one) not
only didn't work but could even result in crashes because invalid iterators in
the menu items list could be used.
Fix this by storing the ranges of all radio groups in wxMenu itself instead of
storing the information about the radio group an item belongs to in the item
itself and by updating this data whenever a new radio item is inserted. Also
get rid of the notion of "current radio group" in wxMenu which doesn't really
make any sense.
Finally add a unit test checking that inserting radio items works as expected.
Closes#13200.

wxMenu::GetTitle() returned a string in GTK+ format (i.e. using underscores
instead of ampersands) instead of the expected wx one.
This is, of course, the right thing to do and it also fixes
wxMenuBar::FindMenuItem() as a side effect.

wxOSX rearranges the standard menu items such as wxID_EXIT and wxID_ABOUT and,
for the former, changes its text to "Quit", so don't use them in the menu unit
test which expects to find the items in the menus to which they were added and
exactly with the labels used when adding them.
