Re: Make string_view operations involving CharT* *not* noexcept and consistent beween string_view and string_view.tcc.

In string_view I botched the noexcept specification of operations like find and friends with CharT* arguments.

I'm a little surprised the inconsistency between string_view and string_view.tcc didn't error. In fact, in one repo thats a little behind trunk it does. I'll continue to look after that issue separately.

I'm fixing this differently, by strengthening the exception specs as
Marc suggested. I haven't addressed Marc's other comments, but we
should do.

Tested x86_64-linux, committed to trunk.

I've also committed this on the 4.9 branch, to fix PR62264
