This implements a helper to get the ptc committee from a state. It uses the cached beacon committees if possible It also implements a helper to compute the largest power of two of a uint64 and a helper to test for nil payload attestation messages

Allow nodes with and without payload in forkchoice (#14288)
* Allow nodes with and without payload in forkchoice This PR takes care of adding nodes to forkchoice that may or may not have a corresponding payload. The rationale is as follows - The node structure is kept almost the same as today. - A zero payload hash is considered as if the node was empty (except for the tree root) - When inserting a node we check what the right parent node would be depending on whether the parent had a payload or not. - For pre-epbs forks all nodes are full, no logic changes except a new steps to gather the parent hash that is needed for block insertion. This PR had to change some core consensus types and interfaces. - It removed the ROBlockEPBS interface and added the corresponding ePBS fields to the ReadOnlyBeaconBlockBody - It moved the setters and getters to epbs dedicated files. It also added a checker for `IsParentFull` on forkchoice that simply checks for the parent hash of the parent node. * review -

Share resources between empty and full nodes (#14517)
* Share resources between empty and full nodes - Share a block structure withing the forkchoice node. The surrounding envelope contains information about the payload presence and the children links, the inner structure contains the usual FFG and parent links. - Reworked setOptimistictoInvalid - Changed the PTC vote logic to have validity handled outside of forkchoice and have forkchoice only keep the total count of votes. * Fix tests * gazelle * Update head twice pre-epbs * only upadte best descendants without computing head * skip forkchoice tests * fix some blockchain tests * Nil optimistic sync fix * only count weight of empty nodes

Process blocks after ePBS (#14611)
These are some of the things that are left to be done - Process the payload - Change stategen to get the poststate of the block and the payload separately - Change the next slot cache to be safe for full/empty -
-
-
-
* Send FCU on epbs * handle late block tasks * deal with reorgs by attestations * save head on regular sync * don't sleep 1 sec
