In browser zksync local node via WASM

[taco-paco]

As native remix plugin uses @ethereumjs/evm in browser for executing transaction and keeping the state.

The same is possible with using era-zk_evm. This would be completely server-less solution. It wouldn't require any maintenance of AWS stack since everything would be executed within user's browser.

With a single tweak era-zk_evm compiled to wasm and hence it is feasible to build on top of this, utilizing existing code for local-node from zksync
