benchmark cost of superchain upgrade

[maurelian]

We should benchmark the cost of the opcm.upgrade() method given the number of chains we'll want to upgrade at once for cycle 34, since deploying new contracts is expensive. Want to make sure that if we're near the block gas limit we know sooner rather than later

This will require expanding the existing test_upgrade_succeeds test so that it can read all standard chains from the SCR and upgrade them all at once.
