Throw an error for an invalid language code or script code.

`lang_code` (required) is the bad code and can be nil or a non-string.

`param` (required) is the name of the parameter in which the code was contained. It can be a string, a number
(for a numeric param, in which case the param will show up in the error message as an ordinal such as
"first" or "second"), or `true` if no parameter can be clearly identified.

`code_desc` (optional) is text describing what the code is; by default, "language code".

`template_text` (optional) is a string specifying the template that generated the error, or a function
to generate this string. If given, it will be displayed in the error message.

`not_real_lang` (optional), if given, indicates that the code is not in the form of a language code
(e.g. it's a script code). Normally, this function checks for things that could plausibly be a language code:
two or three lowercase letters, two or three groups of three lowercase letters with hyphens between them.
If such a pattern is found, a different error message is displayed (indicating an invalid code) than otherwise
(indicating a missing code). If `not_real_lang` is given, this check is suppressed.
