feat(evm): collaborative indexing through txid sharing

[daniel-savu]

Description

• improved indexing reliability by sharing channels between indexing tasks, such that they inform one another when they come across a hyperlane-related transaction
• the receiving end will then get the receipt of that tx and filter it for events relevant to it
• this adds some flexibility to indexing since we can stop relying on watermark cursor entirely: as long as we have one task using sequence indexing, all others can rely on being informed by their channels about what txs to index
• this PR is only for the EVM chains, but can be easily extended

Drive-by changes

• Enforces gas payments for all chains in e2e (previously this only used to be the case for sealevel)
• The channel size is configured per type, similarly to the indexing cursor, in contract_sync/cursors/mod.rs
• Reduces log verbosity is some places, e.g. by manually implementing Debug to exclude fields that aren't relevant to debugging (maybe there's even a macro annotation to exclude, but I haven't checked)
• Renames MpmcReceiver -> BroadcastReceiver

Related issues

• Fixes Hook indexing learns about new messages as they are indexed #3267

Backward compatibility

Testing

e2e tested with the watermark cursor manually disabled

Very nice

Approving but I believe #3833 (comment) may need to be changed before merging
