...
`Unsupported_Flag` was used back when the iterator did not handle
`.Multiline`.

Fix multiline RegEx iteration
...
In `.Multiline` mode:
- `^` is now defined to assert the start of the string or that a "\n" or
"\r" rune was parsed on last VM dispatch.
- `$` is now defined to consume a newline sequence of "\n", "\r", or
"\r\n" or to assert the end of the string.

Hide Regular_Expression values

We don't directly support printing these.
To prevent future issues being raised about the pattern being missing if
someone tries to print one, hide everything.

Remove printing facilities for Regular_Expression
...
The `original_pattern` introduced a tenuous dependency to the expression
value as a whole, and after some consideration, I decided that it would
be better for the developer to manage their own pattern strings.
In the event you need to print the text representation of a pattern,
it's usually better that you manage the memory of it as well.
