feat(anvil): bypass authorization signatures for testing

[shiyasmohd]

Motivation

As mentioned in #11170, We could also provide a way to bypass signature verification for authorization list checks in transactions, enabling simulation without requiring actual signatures.

Solution

• This PR adds a new RPC method anvil_setBypassAuthorizationChecks(bool) that allows developers to bypass authorization signature.
• When enabled, the bypass logic sets an empty authorization list, causing the to skip signature validation.
• When disabled (default), normal signature validation occurs

Closes #11170

thank you! I am not sure we want to add a new endpoint to handle that but rather validate or do not panic when is empty? @zerosnacks @mattsse pls chime in

[mattsse]

hmm, this doesnt make too much sense just yet because this doesnt really allow bypassing the 7702 auths yet

how this should behave is, this should take a signature and a corresponding address that we use as the recovered address of the auth

this is quite similar to

#5381

but we need a way to match the signature to an address
@Soubhik-10 is currently working on #5381 which has a lot of synergies with this task here, so my recommendation is we wait for this task first

but for this pr, we'd then need to "recover" the auths when we're transacting the 7702 tx

[shiyasmohd]

Got it. Thanks for the explanation. Will wait that issue to be solved.

[mattsse]

will provide more pointers once we have #5381

should be straight forward then

[mattsse]

@shiyasmohd this is now unblocked, and we now have access to the cheatsmanager directly in the executor

do you need additional pointers to continue this? lmk

ref #11308

[shiyasmohd]

Thanks @mattsse ! Small additional pointers/hints would help. Just to make sure that I'm going in the right direction.

[mattsse]

so we now already have an anvil_impersonateSignature so we can undo the additional ones in this pr

and then we need to check if the txs are 7702 then we need to check if we have the signatures impersonated

@mattsse Could you review the PR and check if this is the approach you mentioned?
