[libc++] Update CMake dependency for generate_iwyu_mapping.py (#115387)

This script does not depend on the generated headers since those are
already special-cased in header_information.py. Change the dependency
list to depend on header_information.py instead. While looking at this
code also simplify the assignment to libcxx_root inside this script.
