Fix trailing comma in enums of public headers

Compiler warning: comma at end of enumerator list [-Wpedantic]

Note 1: I decided to fix these warnings although trailing commas in
enums are allowed at least since C++11.

Note 2: I fixed only public headers because these headers may be
compiled in user code. To do: check internal headers.
