Adds more log information for effects, such as the reformatted effect code, parameters, techniques and passes. This is useful for tracking down issues and what actually ends up being compiled in the end, without having to guess where the error is actually at, as what is compiled and what was originally there usually differ by a lot.
This information is only logged if libobs is compiled in debug and _DEBUG_SHADERS is defined and not compiled if either of those are not the case.
