Anvil: Make LogCollector configurable via CLI

[adraffy]

Component

Anvil

Describe the feature you would like

I'd like to separate Hardhat console.log() messages from stdout.

Possible ideas:

• custom prefix for console.log (cli, foundry.toml)
• custom prefix for all logs
• json output option {type, line}
• subscribe to console address pseudo-event

Possibly, this feature already exists and I'm blind?

Additional context

No response

If #7773 is likely, possibly this feature could accompany it?

[mattsse]

I think we can make this optional

foundry/crates/anvil/src/eth/backend/mem/inspector.rs

Lines 22 to 23 in 29e5112

	/// collects all `console.sol` logs
	pub log_collector: LogCollector,

with an additional CLI argument

TODO

• Make logcollector optional
• Add a similar flag to configure this via CLI:
  

  foundry/crates/anvil/src/eth/backend/executor.rs

  Line 301 in 29e5112

  if self.enable_steps_tracing {

+1 for this - this would be incredibly useful functionality.

If I understand this change correctly, the CLI option is only to disable the printing?

What if I want to separate the console.logs from the rest of the anvil output?
