Reviewed by Yusuke Suzuki.

Add String / StringView find() overloads that take in a LChar / char instead of
a UChar. It is pretty common to see code in WebKit doing `string.find(':')`.
When the input string is 8-bit, converting ':' to a UChar can be inefficient as
we have optimized versions of StringImpl::find() / WTF::find() that take in a
LChar/char.

Got the idea from:
