Remove custom Utf8.toString implementation
`String::new` is now faster for both ASCII and Unicode strings:
```
Utf8::toString of ascii string took 132 ms
String::new of ascii string took 59 ms
Change = -55.30%
Utf8::toString of unicode string took 410 ms
String::new of unicode string took 280 ms
Change = -31.71%
```
There's at least two reasons for this:
* Java 9 introduced compact strings, which means that `String` is now backed by
a byte array to reduce the memory footprint of ASCII strings.
* Detection of Unicode strings may use HotSpot intrinsics.
