perf: use dyn Database to reduce churn and binary size

Describe the feature you would like

Currently we pass around DB generic everywhere for very little gain. I believe if we used Box<dyn Database> or similar we could remove all of these generics, make Cheatcode object-safe unifying it with DynCheatcode, and generally deduplicate code.

Made possible by recent improvements by @klkvr

Generics currently allow us to recurse inside of inspectors by using such references:

foundry/crates/cheatcodes/src/inspector.rs

Line 92 in 72e44fb

db: &mut ccx.ecx.db as &mut dyn DatabaseExt,

how would we handle this when ccx.ecx.db would be a concrete type?

I think this is the only blocker rn, and one of the biggest pain points which I've also encountered when looking into custom precompiles, because ContextPrecompiles<DB> couldn't be reused when creating those references

[DaniPopes]

In that case ccx.ecx.db is &mut dyn Db or Box<dyn Db> which you can just re-borrow, unless I'm misunderstanding

[klkvr]

right, I think It'd have to be &mut dyn Db then? I believe you can't obtain another Box<dyn Db> without moving out of the ccx.ecx.db
