09690691b6 text/regex: Remove old docmentation and unneeded flag 
`Unsupported_Flag` was used back when the iterator did not handle
`.Multiline`.

35b157ac83 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.

cdc56dc691 Add iterator for core:text/regex. 
Usage:
```odin
haystack := `xxfoobarxfoobarxx`
pattern  := `f(o)ob(ar)`

it := regex.create_iterator(haystack, pattern, {.Global}) or_return
defer regex.destroy(it)

for capture in regex.match(&it) {
	fmt.println(capture)
}
```

d3a51e208d 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.

042f6de478 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.
