Lazy crypto [alt design #1369] (#1371)

Prefer converting int` to uint64 and switch foo.len.uint64 to .len64 (#1375)
* avoid converting from uint64 to int, and where most feasible, int type conversion at all

* .len.uint64 -> .len64

* fix 32-bit compilation

* try keeping state_sim loop variable/bounds as int for 32-bit Azure

* len64 -> lenu64

cache block hash (#1329)
hash_tree_root was turning up when running beacon_node, turns out to be
repeated hash_tree_root invocations - this pr brings them back down to
normal.

this PR caches the root of a block in the SignedBeaconBlock object -
this has the potential downside that even invalid blocks will be hashed
(as part of deserialization) - later, one could imagine delaying this
until checks have passed

there's also some cleanup of the `cat=` logs which were applied randomly
and haphazardly, and to a large degree are duplicated by other
information in the log statements - in particular, topics fulfill the
same role

restore EpochRef and flush statecaches on epoch transitions (#1312)
* restore EpochRef and flush statecaches on epoch transitions

* more targeted cache invalidation

* remove get_empty_per_epoch_cache(); implement simpler but still faster get_beacon_proposer_index()/compute_proposer_index() approach; add some abstraction layer for accessing the shuffled validator indices cache

* reduce integer type conversions

* remove most of rest of integer type conversion in compute_proposer_index()

begin removing plain BeaconState versions of state transition functions (#951)
* remove near-duplicate code paths: process_slot(), process_slots(), and state_transition() for BeaconState are now wrappers around the HashedBeaconState versions

* convert tests/test_state_transition.nim to use HashedBeaconState

* convert mocking infrastructure and spec_block/epoch_processing tests to use HashedBeaconBlock, and remove thus unused process_slot*(state: var BeaconState)

avoid state copy in state transition (#930)
In BlockPool, we keep the head state around, so it's trivial to restore
the temporary state there and keep going as if nothing happened.

This solves 3 problems:
* stack space - the state copy on mainnet is huge
* GC scanning - using stack space for state slows down the GC
significantly
* reckless copying - the copy itself takes a long time

In state_sim, we'll do the same and allocate on heap - this helps a
little with GC - without it, the collection of the temporary strings
created with `toHex` while printing the json dominates the trace.

[WIP] Fake bls at runtime (#735)
* Initial implementation of runtime bls skipping.

Add libnfuzz skipBLSValidation handling, check that it propagates.

* Rename skipBLSValidation -> skipBlsValidation, start skipStateRootValidation
* Replace skipValidation flags with more granular flags.

* Remove comment.
* Also skipMerkleValidation for test_beacon_chain_db.
