  Log Message:
  -----------
  [clang] Turn -Wenum-constexpr-conversion into a hard error (#102364)

The warning has been active for a few releases now, first only in user
code, later in system headers, and finally as an error by default.

Therefore, we believe it is now time to transition into a hard error, as
required by the C++ Standard. The main affected C++ projects have by now
fixed the error, or there's a pending patch for review that does it.

Fixes #59036
