Rewrote wxMSW radio menu items code to support not only appending them.

Browse Source 
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.
