refactor(config-utilities): extract cj/--benchmark-method

Splits the timer dispatch out of cj/benchmark-this-method so it can
be tested with a known method symbol instead of going through
read-string + completing-read. The interactive wrapper still prompts
for both inputs, and now catches the user-error from the internal so
the user-facing behaviour on invalid input is unchanged (the message
goes to the echo area).

Returns the funcall's value to the caller, which is observable
through the timer.
