Add the missing include to fix an error when `cmake_push_check_state()`
is called and incidentally the CMakePushCheckState module is not loaded
by any other check running prior to `FindLibEdit.cmake`:

  CMake Error at /var/no-tmpfs/portage/dev-util/lldb-15.0.4/work/cmake/Modules/FindLibEdit.cmake:24 (cmake_push_check_state):
    Unknown CMake command "cmake_push_check_state".
  Call Stack (most recent call first):
    cmake/modules/LLDBConfig.cmake:52 (find_package)
    cmake/modules/LLDBConfig.cmake:59 (add_optional_dependency)
    CMakeLists.txt:28 (include)
