pw_string: redo pw::string::Length

Moves and renames the existing pw::string::Length to
pw::string::internal::ClampedLength. Instead two new helpers are added:
1) pw::string::NullTerminatedLength(...) which returns the length IFF
   the string is null terminated.
2) pw::string::ClampedCString(...) which returns a string_view of
   the clamped string. This is considered safer compared to strnlen_s
   and the existing internal::ClampedLength implementation, since
   sting_view does not require null termination.
