Allow build and run in repo folder in CMake

[BrettDong]

Summary

Build "Allow build and run in repo folder in CMake"

Purpose of change

When compiling a -O2 build, DATA_DIR_PREFIX macro is defined in CMake build script and there is no way to configure this behaviour. It makes running the game in repo impossible, because C++ code sets internal prefix path to <base_path>/share/cataclysm-dda when the macro is defined, and only a few sub directories can be manually override via launch parameters.

Describe the solution

Add USE_PREFIX_DATA_DIR CMake option defaults to true that controls the behaviour of defining DATA_DIR_PREFIX macro in Release build.
