Odin: add new parser (#4381)
* Odin: add new parser Add a C-crafted parser for the Odin programming language. Supported tag kinds: package, proc, const, var, struct, enum, union, member, enumerator, type, foreign, and more. The parser uses a naming-convention heuristic to distinguish type aliases from constants when the right-hand side of a :: binding is a plain identifier: Ada_Case names are tagged as types, and SCREAMING_SNAKE_CASE names as constants. This is documented in the new ctags-lang-odin(7) man page. https://odin-lang.org Co-authored-by: Masatake YAMATO <yamato@redhat.com>
