We report the byte offset as column number, but devtools assumes them
to be 1-based and subtracts one unconditionally before further
processing it. It's a bit unfortunate, but because of that we have to
just add 1 to the reported column number on the public StackTrace API.

Empty function names are allowed and are output as such, unnamed
functions or functions with no valid UTF-8 name are output as
"<WASM UNNAMED>", while the CallSite object returns null as the
function name.
