Why this should be merged

This PR adds precompile predicate enforcement and onAccept handling that will be used by the warp and shared memory precompiles.

How this works

This PR adds optional Accepter and Predicater interfaces, which are to be optionally implemented by precompile contracts (contract not config or module).

These optional interfaces are NOT intended to be used for custom precompiles outside of this repo and the comments in this PR reflect that. Making his an optional interface removes the need to include it in the precompile gen template and makes it so that a user of the precompilegen template does not even need to see or think about the Accepter or Predicater interface at all.

The predicate is enforced on the relevant access list when calling VerifyWithContext or BuildWithContext.

The Accept handling is performed during block acceptance within plugin/evm/block.go. This is a change from a previous implementation to simplify passing in the backend, so that it does not require changing as much code.

Additionally, the shared memory precompile will need to perform shared memory operations to be committed atomically alongside updating the block that is marked as last accepted.

I spent some time trying to make this logic work within core/blockchain.go, but found that it will be easier to maintain this within plugin/evm/block.go.

How this was tested

This was tested via CI and should be a no-op change since no precompiles currently use the added optional interfaces.

Now that we have the module registration logic, we can implement a test case for this that includes its own implementation of a precompile that uses a predicate and on accept to test this.

How is this documented

This is not intended for end users to touch, so there is not currently an accompanying documentation PR. We should document this in the future, but deferring that for now.

TODO: clearly document new invariants and update precompilegen tutorial with any necessary changes.

Now that this uses optional interfaces for accepter and predicater, this should not require any changes on top of what's already in the precompile refactor.

can we split new predicate context to a variable and then use b.verify(predicateContext, true) for readability? we can also create a function for NewProposerPredicateContext which would take ctx and proporservmblockctx as inputs (not really sure how custom we would want this to be though)

Going to leave this as is, since I don't think this would really improve readability.

I'm a bit confused about the difference between ProposerPredicate vs PrecompilePredicate. will precompiles implement both of these interfaces?

Adding a comment for this. Precompiles should implement ProposerPredicate iff they depend on the ProposerVM Block Context ie. Warp.
