  [C2y] Add octal prefixes, deprecate unprefixed octals (#131626)

WG14 N3353 added support for 0o and 0O as octal literal prefixes. It
also deprecates use of octal literals without a prefix, except for the
literal 0.

This feature is being exposed as an extension in older C language modes
as well as in all C++ language modes.
