feat: eth: Add support for blockHash param in eth_getLogs

[fridrik01]

Fixes: #10781

Context
When working on #10780 I noticed we currently did not support the blockHash param for the eth_getLogs rpc method. If it was specified by user he got confusing results (fromBlock/toBlock were both 0). This PR therefore adds this feature as described in the eth docs

Test plan

Lets consider the tipset 2848101 (hex: 0x2B7565) and get the logs for only that tipset (using fromBlock/toBlock). Since the log output it long lets just count the lines and compute the sha1sum:

curl -s http://localhost:1234/rpc/v1 -X POST -H "Content-Type: application/json" --data '{"method":"eth_getLogs","params":[{"fromBlock": "0x2B7565", "toBlock": "0x2B7565"}],"id":1,"jsonrpc":"2.0"}'|jq|wc -l
231

curl -s http://localhost:1234/rpc/v1 -X POST -H "Content-Type: application/json" --data '{"method":"eth_getLogs","params":[{"fromBlock": "0x2B7565", "toBlock": "0x2B7565"}],"id":1,"jsonrpc":"2.0"}'|jq|sha1sum

Now lets get the same tipset by specifying its blockHash and observe that we get the same results (since using blockHash is the same as specifying fromBlock=toBlock of the tipset):

curl -s http://localhost:1234/rpc/v1 -X POST -H "Content-Type: application/json" --data '{"method":"eth_getLogs","params":[{"blockHash": "0xe8179500429f4c485015a9253e9ee7270a1d3f773fc33ea21d2f007e14623980"}],"id":1,"jsonrpc":"2.0"}'|jq|wc -l
231

curl -s http://localhost:1234/rpc/v1 -X POST -H "Content-Type: application/json" --data '{"method":"eth_getLogs","params":[{"blockHash": "0xe8179500429f4c485015a9253e9ee7270a1d3f773fc33ea21d2f007e14623980"}],"id":1,"jsonrpc":"2.0"}'|jq|sha1sum

I think we need to handle this in

lotus/node/impl/full/eth.go

Line 1173 in 8695fe3

// TODO: derive a tipset hash from eth hash - might need to push this down into the EventFilterManager

(we may not have the block yet, or it may be on another fork)

I think we need to set tipsetCid:

lotus/node/impl/full/eth.go

Line 1163 in 8695fe3

tipsetCid cid.Cid

Which will be matched here:

lotus/chain/events/filter/event.go

Lines 164 to 170 in 8695fe3

	if f.tipsetCid != cid.Undef {
	tsCid, err := te.Cid()
	if err != nil {
	return false
	}
	return f.tipsetCid.Equals(tsCid)
	}
