Optimize DOM HTML serialization for UTF-8 (#16376) 
* Use a direct call for decoding the UTF-8 buffer

* Add fast path for UTF-8 HTML serialization

This patch adds a fast path to the HTML serialization encoding that has
to encode to UTF-8. Because the DOM internally represents all strings
using UTF-8, we only need to validate here.

Tested on Wikipedia English home page on an i7-4790:
```
Benchmark 1: ./sapi/cli/php x.php
  Time (mean ± σ):     516.0 ms ±   6.4 ms    [User: 511.2 ms, System: 3.5 ms]
  Range (min … max):   506.0 ms … 527.1 ms    10 runs

Benchmark 2: ./sapi/cli/php_old x.php
  Time (mean ± σ):     682.8 ms ±   6.5 ms    [User: 676.8 ms, System: 3.8 ms]
  Range (min … max):   675.8 ms … 695.6 ms    10 runs

Summary
  ./sapi/cli/php x.php ran
    1.32 ± 0.02 times faster than ./sapi/cli/php_old x.php
```

(And if you're interested: it takes over a second on my machine using the old DOMDocument class)

Future optimizations are certainly possible, but let's start here.
