feat(ctb): remove genesis output

Removes the startingL2Output from the L2OutputOracle. There's no reason
for this parameter to exist, there's nothing special about the
startingL2Output. It only complicates the initialization process.
Instead, the first output can be published by a proposer just like any
other output.
