Remove requirement on Hash = H256, make Proposer return StorageChanges and Proof (#3860)

Browse Source 
* Extend `Proposer` to optionally generate a proof of the proposal

* Something

* Refactor sr-api to not depend on client anymore

* Fix benches

* Apply suggestions from code review

Co-Authored-By: Tomasz Drwięga <tomusdrw@users.noreply.github.com>

* Apply suggestions from code review

* Introduce new `into_storage_changes` function

* Switch to runtime api for `execute_block` and don't require `H256`
anywhere in the code

* Put the `StorageChanges` into the `Proposal`

* Move the runtime api error to its own trait

* Adds `StorageTransactionCache` to the runtime api

This requires that we add `type NodeBlock = ` to the
`impl_runtime_apis!` macro to work around some bugs in rustc :(

* Remove `type NodeBlock` and switch to a "better" hack

* Start using the transaction cache from the runtime api

* Make it compile

* Move `InMemory` to its own file

* Make all tests work again

* Return block, storage_changes and proof from Blockbuilder::bake()

* Make sure that we use/set `storage_changes` when possible

* Add test

* Fix deadlock

* Remove accidentally added folders

* Introduce `RecordProof` as argument type to be more explicit

* Update client/src/client.rs

* Update primitives/state-machine/src/ext.rs

Co-Authored-By: Tomasz Drwięga <tomusdrw@users.noreply.github.com>

* Integrates review feedback

* Remove `unsafe` usage

* Update client/block-builder/src/lib.rs

Co-Authored-By: Benjamin Kampmann <ben@gnunicorn.org>

* Update client/src/call_executor.rs

* Bump versions
