Removes the `l2geth-exporter` package from the monorepo.
This exposed metrics for the legacy system and is no longer
necessary.

infra: delete

This commit deletes the `infra` directory, which contained a package
called `op-replica`. This package contains docker + k8s tooling to
bring up a legacy system. It is not used and therefore can be deleted.

contracts-bedrock: simplify hh config for mainnet

The legacy integration tests are no longer required. Delete the
directory. This commit is helpful because it will reduce the amount
of tests that need to run in CI.

The legacy integration tests ran against the `ops` docker compose
setup, which brought up the legacy system.

Delete an unused check script from `op-chain-ops`. This script was
added as a sanity check for the migration but it ended up not being
necessary. It can be removed as it will never be used again.

op-batcher: Fix num_frames metrics

The metrics recorded the value of channelBuilder.NumFrames().
But this was only the number of pending frames in the frames
queue.

This PR adds a new method TotalFrames() and separate numFrames
tracking to distinguish between the number of pending frames
and total frames of a channel.
