[jumbo] Give two kNodeNumberLimit constants unique names

In jumbo builds many cc files compile together in the same
translation unit, and thus share the same anonymous namespace.
That means that constants need to have unique names in the
whole build target, and not just unique in the file.

This renames two constants, one that was just added/copied and
one that already existed to give them more descriptive, and
unique, names.
