refactor: adapt to CompilerContract trait type

[elfedy]

Motivation

foundry-rs/compilers#224 would introduce a new type to compilers that involves breaking changes to the api.

Solution

Adapt code to those changes. This is a naive way that hardcodes CompilerContract to be Contract most of the time. We could either adapt the code to be more generic (more desirable from a non evm perspective, but also might be better to delay it for further more targeted PRs) or to have Contract as the default CompilerContract in compilers and potentially remove some boilerplate
