runtime(c): Update syntax and ftplugin files
- highlight more C keywords, including some from C23
Conditionally highlight C23 features:
- #embed, #elifdef and #elifndef preprocessor directives
- predefined macros
- UTF-8 character constants
- binary integer constants, _BitInt literals, and digit separators
- nullptr_t type and associated constant
- decimal real floating-point, bit precise and char types
- typeof operators
Matchit:
- update for new preprocessor directives
fixes: #13667
fixes: #13679
closes: #12984
