feat: txe state machine (#13836)

This PR removes the TXe node with an implementation of a TXe state
machine which combines an aztec node, and a custom archiver /
synchronizer.

Note: Because of the extension of `ArchiverStoreHelper`, there was a
clash of `getBlocks`, in one interface it was expected to receive
`L2Blocks`, and in the other `PublishedBlocks`. To solve this, I have
renamed `getBlocks` on the `ArchiverStoreHelper` to
`getPublishedBlocks`. But doing so I also did the same renaming on the
ArchiverDataStore because it seems to better match the signature
anyways.
