feat(anvil): Set anvil fork cache location (`--cache-path`)

[Szymx95]

Component

Anvil

Describe the feature you would like

Currently the cache location is fixed to ~/.foundry/anvil/rpc. It would really simplify the workflow (for example for running fork tests on CI) if we could set custom directory for the cache location. This is related to #4989 however the issue was related to taking too much space.

Another use case would be to save cache on different drive without the need for symlinking.

Additional context

I am applying to this issue via OnlyDust platform.

My background and how it can be leveraged

I have experience with foundry tooling, and I recently began my journey with Rust. I believe this makes for an excellent opportunity to contribute to the development of blockchain tools.

How I plan on tackling this issue

I would make the Anvil cache location configurable, with a default setting that points to .foundry if no specific location is provided.

Hello, folks!

It seems that for me, anvil ignores --cache-path:

RUST_LOG=debug,cache=trace anvil --cache-path "/tmp/test" --fork-url https://rpc.testnet.fluence.dev --fork-block-number 295905 --no-rate-limit --fork-chain-id 52164803
