Change Details

``` HexStr can be called with anything that bas begin() and end() functions, so clean up the redundant calls. (context: I tried to convert HexStr to use span, but this turns out to be somewhat more involved than I thought, because of the limitation to pre-c++17 Span lacking iterator-based constructor) . This commit is a first step which stands on its own though) ``` Backport of core PR19373.
