The printing functionality part of `reftable/dump.c` is really only used by our "dump-reftable" test helper. It is certainly not generic logic that is useful to anybody outside of Git, and the format it generates is quite specific. Still, parts of it are used in our test suite and the output may be useful to take a peek into reftable stacks, tables and blocks. So while it does not make sense to expose this as part of the reftable library, it does make sense to keep it around. Inline the `reftable_dump_main()` function into the "dump-reftable" test helper. This clarifies that its format is subject to change and not part of our public interface. Furthermore, this allows us to iterate on the implementation in subsequent patches.
