Upgrade dependencies (#2513)

## Proposed Changes

* Consolidate Tokio versions: everything now uses the latest v1.10.0, no more `tokio-compat`.
* Many semver-compatible changes via `cargo update`. Notably this upgrades from the yanked v0.8.0 version of crossbeam-deque which is present in v1.5.0-rc.0
* Many semver incompatible upgrades via `cargo upgrades` and `cargo upgrade --workspace pkg_name`. Notable ommissions:
    - Prometheus, to be handled separately: https://github.com/sigp/lighthouse/issues/2485
    - `rand`, `rand_xorshift`: the libsecp256k1 package requires 0.7.x, so we'll stick with that for now
    - `ethereum-types` is pinned at 0.11.0 because that's what `web3` is using and it seems nice to have just a single version
    
## Additional Info

We still have two versions of `libp2p-core` due to `discv5` depending on the v0.29.0 release rather than `master`. AFAIK it should be OK to release in this state (cc @AgeManning )
