* Removes spawn_blocking in flush_spawning methods

* Logs warning and returns error for RecvErrors

* Uses BoxError in proof verifiers

* Adds async spawn_fifo fns

* Updates verify_single_spawning and flush_spawning methods to use new async spawn_fifo fns

* Removes outdated TODOs and docs.

feat(verify): Concurrently verify proof and signature batches (#4776)
* Initialize the rayon threadpool with a new config for CPU-bound threads

* Verify proofs and signatures on the rayon thread pool

* Only spawn one concurrent batch per verifier, for now

* Allow tower-batch to queue multiple batches

* Fix up a potentially incorrect comment

* Rename some variables for concurrent batches

* Spawn multiple batches concurrently, without any limits

* Simplify batch worker loop using OptionFuture

* Clear pending batches once they finish

* Stop accepting new items when we're at the concurrent batch limit

* Fail queued requests on drop

* Move pending_items and the batch timer into the worker struct

* Add worker fields to batch trace logs

* Run docker tests on PR series

* During full verification, process 20 blocks concurrently

* Remove an outdated comment about yielding to other tasks

fix(batch): Improve batch verifier async, correctness, and performance (#4750)
* Use a new channel for each batch

* Prefer the batch timer if there are also new batch requests

* Allow other tasks to run after each batch

* Label each batch worker with the verifier's type

* Rename Handle to ErrorHandle, and fix up some docs

* Check batch worker tasks for panics and task termination

* Use tokio's PollSemaphore instead of an outdated Semaphore impl

* Run all verifier cryptography on a blocking thread

Also use a new verifier channel for each batch.

* Make flush and drop behaviour consistent for all verifiers

* Partly fix an incorrect NU5 test

* Switch batch tests to the multi-threaded runtime

* Export all verifier primitive modules from zebra-consensus

* Remove outdated test code in tower-batch

* Use a watch channel to send batch verifier results

* Use spawn_blocking for batch fallback verifiers

* Spawn cryptography batches onto blocking tokio threads

* Use smaller batches for halo2

* Minor tower-batch cleanups

* Fix doc link in zebra-test

* Drop previous permit before acquiring another to avoid a deadlock edge case

Async Halo2 verifier service (#2645)
* First pass at async Halo2 verification service

Stubs out a batch verifier for the future.
The dependencies for orchard, halo2, librustzcash, zcash_primitives, have
not been resolved.

* Halo2 verifier service and test

* Remove redundant conversion

* Test async halo2 verifier service with pre-computed Orchard shielded data test vectors

* Fix typo

* Shorten tower::Service trait constraints for Halo2 verifier tests

* Remove commented out trait constraints

* .expect() vs .unwrap() to parse orchard::redpallas::VerificationKey

* Use .to_vec() for some test vectors

* Fix self-referential Display impl

* Fix deps

* Distinguish orchard vs zebra_chain::orchard imports

* Add test that halo2 verifier fails with malformed proof inputs

* Use thiserror for Halo2Error

* Use ZcashFoundation/orchard instead of dconnolly/orchard

* Add a link to the issue to remove the zfnd fork of orchard crate

* Update zebra-consensus/Cargo.toml
