* node/approval-voting: Introduce Backend trait and Overlaybackend

This commit introduces a Backend trait and attempts to move away
from the Action model via an OverlayBackend as in the ChainSelection
subsystem.

* node/approval-voting: Add WriteOps for StoredBlockRange and BlocksAtHeight

* node/approval-voting: Add load_all_blocks to overlay

* node/approval-voting: Get all module tests to pass.

This commit modifies all tests to ensure tests are passing.

* node/approval-voting: Address oversights in the previous commit

This commit addresses some oversights in the prior commit.

1. Inner errors in backend.write were swallowed
2. One-off write functions removed to avoid useless abstraction
3. Touch-ups in general

* node/approval-voting: Move from TestDB to dyn KeyValueDB

This commit removes the TestDB from tests.rs and replaces it with
an in-memory kvdb.

* node/approval-voting: Address feedback

* node/approval-voting: Add license to ops.rs

* node/approval-voting: Address second-pass feedback

* Add TODO

* node/approval-voting: Bump spec_version

* node/approval-voting: Address final comments.

* update benchmark

* add host function

* update Substrate

* fix unused

* Companion for Decouple Staking and Election - Part 3: Signed Phase

https://github.com/paritytech/substrate/pull/7910

* remove some config types

* allow up to 5 signed submissions on polkadot and kusama

* signed phase is equal induration to unsigned phase

* use chain defaults for base and per-byte deposits; >= 16 SignedMaxSubmissions

* use a small but non-trivial solution reward

* reduce signed deposit per byte fee

* reduce signed reward, adjust polkadot expected soln size

* copy submit benchmark from substrate

* demo calculating an appropriate fee for the signed reward

Unfortunately, this doesn't work: it needs to be a constant function,
and AFAIK there's no way to make a trait method constant.

* SignedRewardBase is 1.5x the fee to submit a signed solution

* all chains use deposit byte of base per 50k

* update Substrate

* cargo update -p pallet-election-provider-multi-phase
