When a block is introduced to the system both via REST and gossip at the
same time, we will call `storeBlock` from two locations leading to a
dupliace check race condition as we wait for the EL.
This issue may manifest in particular when using an external block
builder that itself publishes the block onto the gossip network.
* refactor enqueue flow
* simplify calling `addBlock`
* complete request manager verifier future for blobless blocks
* re-verify parent conditions before adding block
among other things, it might have gone stale or finalized between one
call and the other
```
Essential changes:
security bugfix in Go bindings
run-time switch in portable build
no-std support [exercised with limited stack size of 56K]
serde support
blst_miller_loop_n interface, with parallelized Rust and Go
counterparts
optional blst_fr_pentaroot subroutine
Emscripten bindings
hardened security on non-asm platforms
```
* move file loading out of timed ncli section to focus benchmark on
deserialization rather than disk loading
* JSON loading fix included in bump, but does not practically happen
since we generally don't load hashlist from JSON
every attestation is processed with a new wall time so we end up
iterating over all attestations for every attestation we queue - this is
4% of cpu time on a subscribe-all-subnets node
* remove redundant zero checks - block root must be an existing block
and therefore cannot be zero
* simplify "hasn't-voted" check to root only (isZeroMemory is dubiously
implemented for objects)
* Add support for POST /eth/v2/beacon/blocks
* More descriptive errors
* Address review feedback
* Return 500 (not 400) for a missing implementation case
We know the aggregate publickey of a fully participating sync committee.
Because participation is typically very high (>95%), it is faster to
start from that aggregate publickey and subtract the individual keys of
non-participants, than summing up all the participating pubkeys.
With the gnosis binary, building all targets sometimes exceeds the 40m.
Bump timeout to 50m.

To obtain the correct `transactions_root` and `withdrawals_root`,
it is necessary to process execution block header. Light client updates
don't contain the correct MPT roots.
Port 9952 sometimes seems blocked, maybe by another Status project
being tested on the same host, or by UPS process, or maybe it needs
SO_REUSEPORT as well?
Switch to 9962 for now to see if that improves things.

Using `create` with objects containing managed objects is broken:

Switch to a safer pattern based on `new+GC_ref`/`GC_unref` instead.
