chore: introduce versioned ExecutionPayload

[Rjected]

This refactors the ExecutionPayloadEnvelope type into version-specific types, which no longer have Options for post-V1 fields. These types should map to the types from the engine spec.

Solves the TODO:

// TODO(rjected): we could improve this by wrapping envelope / payload types by version, so we can
// have explicitly versioned return types for getPayload. Then BuiltPayload could essentially be a
// builder for those types, and it would not be possible to e.g. return cancun fields for a
// pre-cancun endpoint.

Specifically this introduces:

• ExecutionPayloadV1
• ExecutionPayloadV2
• ExecutionPayloadV3
• ExecutionPayloadEnvelopeV2
• ExecutionPayloadEnvelopeV3

cool!

because we want standalone rpc types, we want the TryFrom conversions separately, I think in the rpc compat crate

[mattsse]

the clone is not required if we call into first

[mattsse]

we want this as functions instead because
we want standalone rpc types eventually

see #4186
