contracts-bedrock: test deploy script

This updates the tests to use the deploy script to set up the
L1 contracts. This ensures that the tests are testing a setup
as close as possible as to what ends up in production. The
L2 contracts are setup in a unified place but as not set up
behind proxies yet. This has been an issue but should be addressed
when we have the ability to import the output of the L2 genesis
generation script.

Any circleci machines that run `forge build` oom when the machine
is not an xlarge. This means that many jobs need to be bumped up
to that size for them to run until the end.

`CommonTest` is heavily modified and cleaned up. A lot of code was
deleted and a good amount of the code that was added is from moving
things to kwargs sytax from not. Some tests were converted from
being regular tests into fuzz tests.

 # `OptimismPortal` Invariants
 
 ## Deposits of any value should always succeed unless `_to` = `address(0)` or `_isCreation` = `true`.
-**Test:** [`OptimismPortal.t.sol#L148`](../test/invariants/OptimismPortal.t.sol#L148)
+**Test:** [`OptimismPortal.t.sol#L151`](../test/invariants/OptimismPortal.t.sol#L151)
 
 All deposits, barring creation transactions and transactions sent to `address(0)`, should always succeed. 
 
 ## `finalizeWithdrawalTransaction` should revert if the finalization period has not elapsed.
-**Test:** [`OptimismPortal.t.sol#L171`](../test/invariants/OptimismPortal.t.sol#L171)
+**Test:** [`OptimismPortal.t.sol#L174`](../test/invariants/OptimismPortal.t.sol#L174)
 
 A withdrawal that has been proven should not be able to be finalized until after the finalization period has elapsed. 
 
 ## `finalizeWithdrawalTransaction` should revert if the withdrawal has already been finalized.
-**Test:** [`OptimismPortal.t.sol#L201`](../test/invariants/OptimismPortal.t.sol#L201)
+**Test:** [`OptimismPortal.t.sol#L204`](../test/invariants/OptimismPortal.t.sol#L204)
 
 Ensures that there is no chain of calls that can be made that allows a withdrawal to be finalized twice. 
 
 ## A withdrawal should **always** be able to be finalized `FINALIZATION_PERIOD_SECONDS` after it was successfully proven.
-**Test:** [`OptimismPortal.t.sol#L230`](../test/invariants/OptimismPortal.t.sol#L230)
+**Test:** [`OptimismPortal.t.sol#L233`](../test/invariants/OptimismPortal.t.sol#L233)
 
 This invariant asserts that there is no chain of calls that can be made that will prevent a withdrawal from being finalized exactly `FINALIZATION_PERIOD_SECONDS` after it was successfully proven.
