Bug 1613013 part 3. Annotate TypeErrors and RangeErrors from WebIDL implementations with the method they come from. r=peterv
Please review the changes to Errors.msg very carefully. I caught a number of
mistakes there in self-review (e.g. not renumbering replacement markers
correctly when I added {0} to the beginnings of strings), and my confidence
that I caught them all is only middling.
A few lines (MSG_USELESS_SETTIMEOUT, MSG_TYPEDARRAY_IS_DETACHED,
MSG_NOT_SUBMIT_BUTTON) were removed from Errors.msg either because they were
already unused or because they either were single-user constant strings or
became such in the new setup and we could just use the string version of
ThrowTypeError.
