[Feature] Declarative Calls Feedback

[melotik]

Description

I spent some time trying to add declarative calls (https://github.com/graphprotocol/graph-node/pull/5264) to messari's compound v3 subgraph as it uses a lot of eth_calls. I wasn't able to fully test any of this yet due to this blocker (https://github.com/graphprotocol/graph-node/issues/5444), however I had some feedback or requests for use cases that showed up when I was working to cut over the subgraph to use declarative calls.

• Using an eth_call as input for another eth_call, here is a real example:

const utilization = cometContract.getUtilization();
const borrowRate = cometContract.getBorrowRate(utilization).toBigDecimal();
const supplyRate = cometContract.getSupplyRate(utilization).toBigDecimal();

• Multiple calls on one handler for the same function call with different input:

calls:
	Comet.totalsBasic: Comet[event.address].totalsBasic(event.params.liquidator)
	Come.totalsBasic: Comet[event.address].totalsBasic(event.params.borrower)

Note: This may be possible to do already, but I am not sure

Are you aware of any blockers that must be resolved before implementing this feature? If so, which? Link to any relevant GitHub issues.
