Make a distinction between generated headers and "translated" headers. This is important to support build-time dependencies when headers are updated. Generated headers are those which contain build-time feature specifications, like `git2_features.h` that are internal to the build and `experimental.h` that contain API information. Translated headers are the headers that are in `include/git2`, but may be translated to have a unique prefix like `incklude/git2-experimental`. This distinction is important so that the CMakeFiles.txt depend on the in-tree include files (`src/include`) and the generated header files _but not_ the translated header files. Otherwise there are two `pack.h` and it's unclear whether the in-tree build is targeting the one in `src/include` or the one in the build tree. Without this, updating an in-tree header file like `pack.h` would not cause a rebuild of its dependencies.
