Fix Encoding.GetChars return value

[ltrzesniewski]

Summary

Encoding.GetChars(ReadOnlySpan<Byte>, Span<Char>) returns the number of written chars, not the number of decoded bytes as currently documented.

See the default implementation, which delegates to the GetChars(Byte*, Int32, Char*, Int32) overload.

I used the same text as in Decoder.GetChars(ReadOnlySpan<Byte>, Span<Char>, Boolean).
