Reviewed by Mark Lam.

* Source/WTF/wtf/text/StringImpl.h:
(WTF::StringImpl::characters16 const): Allow calling this on the empty string without asserting.
There is no problem returning the 8-bit character pointer as a 16-bit character pointer when the
length is zero; the pointer will never be dereferenced.
* Source/WTF/wtf/text/StringView.h:
(WTF::StringView::characters16 const): Ditto.
