Check init sync before getting payload attributes (#13479)
* Check init sync before getting payload attributes

This PR adds a helper to forkchoice to return the delay of the latest
imported block. It also adds a helper with an heuristic to check if the
node is during init sync. If the highest imported node was imported with
a delay of less than an epoch then the node is considered in regular
sync. If on the other hand, in addition the highest imported node is
more than two epochs old, then the node is considered in init Sync.

The helper to check this only uses forkchoice and therefore requires a
read lock. There are four paths to call this

1) During regular block processing, we defer a function to send the
   second FCU call with attributes. This function may not be called at
all if we are not regularly syncing
2) During regular block processing, we check in the path
   `postBlockProces->getFCUArgs->computePayloadAttributes` the payload
attributes if we are syncing a late block. In this case forkchoice is
already locked and we add a call in `getFCUArgs` to return early if not
regularly syncing
3) During handling of late blocks on `lateBlockTasks` we simply return
   early if not in regular sync (This is the biggest change as it takes
a longer FC lock for lateBlockTasks)
4) On Attestation processing, in UpdateHead, we are already locked so we
   just add a check to not update head on this path if not regularly
syncing.
