    Fix Version.h not found when CMake binary directory is customized (#13324)
    
    ### Motivation
    
    When I build C++ tests on my local env, the following error happened.
    
    ```
    tests/VersionTest.cc:19:10: fatal error: 'pulsar/Version.h' file not found
    #include <pulsar/Version.h>
    ```
    
    It's because I specified another directory as CMake directory.
    
    ```bash
    mkdir _builds && cd _builds && cmake ..
    ```
    
    After https://github.com/apache/pulsar/pull/12769, the `Version.h` is 
generated under `${CMAKE_BINARY_DIR}/include/pulsar` directory but it's not 
included in `CMakeLists.txt`. CI works well because it's built in the default 
CMake directory so that `CMAKE_BINARY_DIR` is the same with `CMAKE_SOURCE_DIR`, 
which is included.
    
    ### Modifications
    
    Add the `${CMAKE_BINARY_DIR}/include` to `included_directories`.
    
    (cherry picked from commit ca37e67211feda4f7e0984e6414e707f1c1dfd07)
