feat: Add trace filter API

[snissn]

Proposed Changes

• Add json RPC support for trace_filter to lotus

• This code uses a default value of latest for FromBlock and ToBlock if either are not provided. These are used to iterate through blocks and a filter is applied.

• The spec lists FromBlock and ToBlock as optional but i think in practice most use cases include will them. I'm not sure how to implement this function without a block range because of the way the data is organized.

TODO:

• Implement support for blocks specified by "Latest"

@snissn I was just going looking for source of the reference implementation of this but I've noticed this isn't in go-ethereum, only in "openethereum and erigon". So with one of those deprecated we only have erigon. I know little of the eth ecosystem, but in how widespread use is erigon, and how common is this call? Are people begging for this in Filecoin? And do we want to be signing up to be supporting even more methods than go-ethereum does when we have a fraction of the ability to support them?

And btw the behaviour of default values seems to mostly be in here: https://github.com/ledgerwatch/erigon/blob/5ee7f351f5361ac1070b28f1f25455b6d00905af/turbo/jsonrpc/trace_filtering.go#L286-L316

Plus a bunch more behavioural things in filterV3 below it.

From default 0, To default to head (I think). Both inclusive. I'm also not seeing a limit in there, which seems a bit off. Surely this doesn't let you call for 0 to head and it just streams as much as it has? Maybe there's a time limit or byte limit on output somewhere on the RPC layer that limits this.

This is an expensive API as Rodd's profiling shows and I think it's hard to guesstimate the default value of allowed traces for a single call without knowing usage patterns etc. Bets to keep a sane value of say 500 and then depend on user feedback to change it when we do get feedback. RPC providers can always change the default for specific use cases/users they need to support.
