Add test coverage support for Vyper contracts

[pcaversaccio]

Component

Forge

Describe the feature you would like

Since @gakonst deliberately asked for it here ;-), I would love to see a tooling around test coverage for Vyper contracts using the Vyper deployer approach via ffi. That's one of the missing pieces in my snekmate repo. I reckon that the same (or similar) solution for this feature could also be carried over to Huff or Fe contracts later.

Additional context

My version of the VyperDeployer can be found here.

Hi @pcaversaccio!

With Vyper support having landed in Foundry would be great to know how if this aspect is sufficiently addressed and if you have run into any issues when using forge coverage with Vyper so far

Well forge coverage doesn't work at all in Foundry: https://book.getfoundry.sh/config/vyper#5-limitations.
