* Use already injected RenderDoc dll, or load it from default location
- on Windows, if the process was launched from RenderDoc and the dll is already injected, use it
- otherwise try to load the dll from the default installation path in Program Files
- doesn't need the dll to be copied next to the exe or in the system PATH, which is not the supported way to do it according to BaldurK - see https://github.com/baldurk/renderdoc/issues/2279#issuecomment-844588691
* Restore previous implementation of findModule
* Address PR feedback
