Add static_assert to spanReinterpretCast<>() to prevent unnecessary casts.

Idea from Darin Adler here: <https://github.com/WebKit/WebKit/pull/35601#discussion_r1811793553>

This was seen once in Source/WTF/wtf/text/AtomStringImpl.cpp prior to fixing Bug 281944:

```
RefPtr<AtomStringImpl> AtomStringImpl::add(std::span<const char8_t> characters)
{
    HashedUTF8Characters buffer { characters, computeUTF16LengthWithHash(spanReinterpretCast<const char8_t>(characters)) };
    [...]
```
