[sui-tool] dump-packages uses GraphQL (MystenLabs#18337)

## Description

Replace the original implementation of the dump-packages command (which
requires access to an indexer database) with an implementation that
reads from a GraphQL service. The former is not readily accessible, but
the latter should be.

The new tool is also able to run incrementally: Fetching only packages
created before a certain checkpoint, or pick up where a previous
invocation took off to fetch new packages that were introduced since.

## Test plan

Ran a test invocation, on our experimental read replica. With a max page
size of 200, I was able to fetch 17000 packages (all the packages at the
time the read replica was created) in 3 minutes.
