EGD-3393 UTF8 Unicode fixup for ostry cień mgły
* We are working in little endian, string notation doest't care
* UTF8 cleanup - removed reinterpret casts, removed unused code, and added {}
* added forward declaration for ostream and moved operator<< to cpp
* Removed dead code
* Fixed crash on out of memory access in Renderer on draw char
* Fixed tests failing - there was no test for operator==
* Added changelog
Add proper catch2 support:
- add catch2 as a submodule
- add cmake function to add test easily
- discover each test in test binary
- remove copies of catch.hpp
- do not try to process tests for rt1051
Do not test internals of utf8, only public interface (nasty bugs could
occur otherwise).
