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.

Adds pw::string::Copy helper methods as a safer alternative to
std::strncpy which unfortunately does not always null terminate.
In addition, the existing StringCopy methods are renamed to
StringOrNullCopy to denote that they support nullptr source strings
unlike pw::string::Copy.
