c++: add deprecation notice for -fconcepts-ts
We plan to remove -fconcepts-ts in GCC 15 and thus remove the flag_concepts_ts
code. This note is an admonishing reminder to convert the Concepts TS
code to C++20 Concepts.
gcc/c-family/ChangeLog:
* c-opts.cc (c_common_post_options): Add an inform saying that
-fconcepts-ts is deprecated and will be removed in GCC 15.
gcc/ChangeLog:
* doc/invoke.texi: Mention that -fconcepts-ts was deprecated in GCC 14.
