RFC (from L2s) on BLS Subgroup checks

The L1 core devs are having discussions around subgroup checks for the BLS precompiles scheduled to be included via EIP-2537 in the Pectra upgrade. The issue is including a subgroup check into the MSM doing so means that we largely loose the sub-linear benefits of the MSM as the sub-group checks start to be a large component of the total computation. That said, they do have to be done at some point for every input, so the question is whether it is worth building them into the pre-compile to avoid having a foot-gun or whether they would be used in a way where the costs of doing the subgroup checks on every MSM (even if already verified) is not worth it. Proposals Some of the ideas proposed are: a. Just have the subgroup check be included b. have a flag to disable the check as a part of the precompile c. have two separate precompiles, one with and one without the check d. no subgroup checks, and we ask devs to be very careful
