determine UTF-8 at compile-time (#768)

* use str::EncodedStringView to mange XML

* add an EncodedString that that stores the encoding of the string

* fixed unit-test that was sometimes failing on Windows

* overloads for std::u16string and std::u8string

* open up just one hole in EncodedStringView, not two

* put w1252string() in details:: too

* provide a "PlatformEncoding" value

* fix broken EncodedString

* use EncodedString to better indicate our intentions (and test EncodedString itsefl)

* "struct details" is a bit goofy, use the normal "friend" mechanism instead

* since EncodedString is now a friend of EncodedStringView, just to do the work there

* gsl::narrow instead of static_cast

* begin work on UTF-16/UTF-32 conversions

* prepare to use EncodedString

* older C++ compilers don't like so much "constexpr"

* to_u8string() from std::wstring

* get a std::wstring from EncodedStringView

* U8StringStream and W1252StringStream

* hookup StringStreamT routines

* using StringStreamT for all implementations

* don't create a temporary UTF-8 string for to_u16string()/to_u32string()
