feat(foundry-cli::utils): add new allocators + tracing features

Describe the feature you would like

Following #10523 (abstract global allocator in foundry-cli), we could extend the allocator module to support multiple allocators and tracing.

Proposed Changes

1. Add support for multiple allocators:

   • jemalloc (current)
   • mimalloc
   • snmalloc

2. New feature flags:

[features]
default = ["jemalloc"]
jemalloc = ["foundry-cli/jemalloc"]
mimalloc = ["foundry-cli/mimalloc"]
snmalloc = ["foundry-cli/snmalloc"]
tracy-allocator = ["foundry-cli/tracy-allocator"]

Questions

1. Which allocators to implement?
2. Should we include tracy-allocator feature?

I would like to be assigned to implement this feature if the team considers it valuable.

I'm not sure how relevant the differences between the allocators are in the context of Foundry but it could be worth benchmarking them. Given that Foundry ships as a unified toolset rather than an SDK I would prefer we consolidate on one. The tracy allocator could be of use.

In Solar, I've found that mimalloc is on-par or faster than jemalloc while being smaller in binary size and faster to compile. Other allocators were generally than these two.
We should add mimalloc as an non-default option, and tracy-allocator.
Definitely worth benchmarking at least mimalloc before changing any defaults.
