feat: add aztec profile command with gate count profiling

[nchamo]

Summary

Adds a new aztec profile command that profiles compiled Aztec artifacts. The first subcommand, aztec profile gates, displays gate counts for all compiled contracts and circuits in a target directory.

This is the beginning of a profiling suite for Aztec developers. The flamegraph command will be added as a subcommand under aztec profile next, consolidating all profiling tools in one place. Running bare aztec profile shows help listing available subcommands.

Sample output (on the test workspace with a simple contract and two circuits):

Gate counts:
------------------------------------------------------------------------
simple_circuit                                                      45
simple_circuit_2                                                    46
simple_contract-SimpleContract::another_private_function         5,616
simple_contract-SimpleContract::private_function                 5,540
------------------------------------------------------------------------
Total: 4 circuit(s)

Addresses #20323

Commented on other one, but why not aztec simulate?

[ludamad]

and why does this not touch yarn-project/cli-wallet/src/utils/profiling.ts

[nchamo]

Hey @ludamad !

Sorry, had to delete the other PR I was having issues with it. What do you say if we discuss the need (or not) for this change at #20323 directly?

Then we can circle back and discuss the implementation here

[ludamad]

good with it after chatting

[mverzilli]

Neat!

@nchamo in our merge train PR the profile_gates.test.ts test is failing.

What is weird that locally it passes:

Do you have a clue why this might be the case?

Could it be some stale artifacts in CI issue or something? (this tends to be the case when a failure is only in CI)

Can help debug.

[nchamo]

@benesjan I run into the same issue on my CI. I think that the compile.test and profile_gates.test.ts mess with each other since both compile + clean things up

I'm making them run sequentially here:
#20741

[benesjan]

Perfect. Thanks!
