Do not define basic_string_view::to_string
gdb's copy of basic_string_view includes a to_string method. However,
according to cppreference, this is not a method on the real
std::basic_string_view:
https://en.cppreference.com/w/cpp/string/basic_string_view
This difference matters because gdb_string_view.h will use the
standard implementation when built with a C++17 or later. This caused
PR build/26183.
This patch fixes the problem by changing the method to be a standalone
helper function, and then rewriting the uses. Tested by rebuilding
with a version of GCC that defaults to C++17.
(Note that the build still is not clean; and also I noticed that the
libstdc++ string_view forbids the use of nullptr ... I wonder if gdb
violates that.)
