Bound the filter of init SC events by blocks

When querying the init event for each smart contract, bound the search from
block genesis-24h to block genesis.  Otherwise, this query in geth synced to
mainnet takes too long.

Update TxSel selection to prioritize the forgable

Previous to this commit, there were cases where being
len(nonForgableL2Txs)>maxL2Txs and nonForgableL2Txs have bigger fee than
forgableL2Txs, the forgableTxs where never forged, neither the
nonForgableTxs.  Now, the TxSelector first forges the forgableTxs (which
are forgable for the initial state of the accounts (balances & nonces),
and then the nonForgableL2Txs, which may be unblocked once the forgable
ones have been processed.

Fix Synchronizer not setting slot.ForgerCommitment to true

New configuration Coordinator configuration parameter `ForgeOncePerSlotIfTxs`:
ForgeOncePerSlotIfTxs will make the coordinator forge at most one batch per
slot, only if there are included txs in that batch, or pending l1UserTxs in the
smart contract.  Setting this parameter overrides `ForgeDelay`,
`ForgeNoTxsDelay`, `MustForgeAtSlotDeadline` and `IgnoreSlotCommitment`.

Also restructure a bit the functions that check policies to decide whether or
not to forge a batch.

separated the policy to decide if we forge batch or not
