Report parse warns and compile errs when running script files (#13369)

# Description

Report parse warnings and compile errors when running script files.

It's useful to report this information to script authors and users so
they can know if they need to update something in the near future.

I also found that moving some errors from eval to compile time meant
some error tests can fail (in `tests/repl`) so this is a good idea to
keep those passing.
