feat(evm): Block/Tx/Cfg setters traits

[mablr]

Motivation

• Foundry requires mutable Block/Tx/Cfg for cheatcodes.
• We want Foundry to support multiple EVMs: Eth, Op and Tempo
• For that we need to get rid of concrete fields mutations, and use instead generic setters
• But ... revm provides only getters traits Block/Transaction/Cfg

Solution

• Introduced FoundryBlock/FoundryTransaction/FoundryCfg, respectively extending revm's Block/Transaction/Cfg.
• Enforced through FoundryContextExt: ContextTr<Block: FoundryBlock, Tx: FoundryTransaction, Cfg: FoundryCfg>
• Provides idiomatic patterns like ctx.cfg_mut().set_spec(spec_id)

The extension of these traits for Tempo will follow a logic similar to #13512, with "no-op" defaults.

directionally looks good, left some questions though
