Description

Fixes compilation when setting the C++ standard to 20+ by disabling char8_t.

Note that while #9183 introduces a deprecation warning in C++20 that gets treated as error, char8_t also causes failure in other cases where std::filesystem is used, such as obs-app.cpp.

Motivation and Context

We might want to start using C++20 at some point, and the less said about char8_t the better.

How Has This Been Tested?

Compiled on Windows with CMAKE_CXX_STANDARD set to 20.
