fix `(string-length)` to return chars instead of utf-8 bytes (#518)

* return number of chars in string-length instead of utf-8 codepoints

the scheme spec states, that `(string-length)` should "return the
number of characters in the given string".

additionally all other scheme dialects i've tested return the characters
instead of utf-8 codepoints.

```
$ racket
> (string-length "✅")
1
```

* move string_append.scm tests to string.scm, add assert-equal!

no reason to add the few string-length tests into a separate file,
always deduplicating assert-equal! procedure, so just add it into the
same test.

* add (string-length) tests

* add a utf8-length to match the previous behaviour of string-length
