asarium feda97c148 Properly handle invalid UTF-8 sequences in NanoVG ...

The original issue was reported by Novachen in #1754 where a significant
slowdown was encountered in the controls menu (Ship and Misc tabs). I
traced the cause of the slowdown to repeated uploads of the NanoVG font
atlas texture even though no changes were necessary.

The root cause of the issue was that NanoVG did not handle invalid UTF-8
sequences at the end of a string properly. The UTF-8 decoder returned a
success code even though no code point was decoded which lead the rest
of the code to believe that the font atlas needed to be recreated.

This fixes #1754 by properly handling that case.

This also fixed an assertion failure if NanoVG was asked to render
2D elements without any vertices.
