  [C2y] Implement WG14 N3411 (#130180)

This paper (https://www.open-std.org/jtc1/sc22/wg14/www/docs/n3411.pdf)
allows a source file to end without a newline. Clang has supported this
as a conforming extension for a long time, so this suppresses the
diagnotic in C2y mode but continues to diagnose as an extension in
earlier language modes. It also continues to diagnose if the user passes
-Wnewline-eof explicitly.
