feat: Revert all previous changes and prepare for crash debugging

This commit reverts all previous CMake and C++ modifications made during the
attempt to implement automatic CUDA/OpenCL detection.

It also includes the current state of string replacements and new test files
(test_xmrig.cpp, dll_injector.cpp, dll_injectorWORKING.cpp) for debugging
application crashes.

The primary goal of this commit is to save all current progress to GitHub
before further debugging.
