Adds a limit to prevent calldata larger than 120kb. Unsafe
blocks contain the deposit transactions and when there is
no upper bound on the calldata size, it is possible for a
single transaction to cause the p2p gossip to consume
far more bandwidth than necessary.

Prevent users from sending cross domain messages with too small
of a gas limit. Users must pay for resources they consume. The
L2 network must store deposit transactions in their history and
they are also included in the p2p gossip of unsafe blocks.
A linearly increasing requirement based on the calldata size
is introduced. A base of 21k minimum gas limit is required when
there is no gas limit, the formula `calldata.length * 16 + 21000`
is used to enforce a min gas limit.

The larger the gaslimit, the more ether that is burnt on L1.

fix: withdrawal gas limit

Co-authored-by: Maurelian <maurelian@protonmail.ch>

Updates the gas limit in the migrated withdrawals codepath
to ensure that enough gas is used.

Don't revert if `relayMessage` does not have enough gas to perform the external call + finish execution
