Sergei Shulepov d4fdbf7db9 Clean up PersistedValidationData (#2353 )

* PVD: `block_number`->`relay_parent_number`

* ValidationParams: `relay_chain_height`->`relay_parent_number`

* Expose DMQ MQC hash as a well-known-key

This way the relay storage merkle proofs will be able to obtain the DMQ
MQC hash and we will be able to remove the it from the
PersistedValidationData struct.

* PersistedValidationData: Remove HRMP MQC heads

* PersistedValidationData: Remove `dmq_mqc_head`

* Expose the HRMP ingress channel index as a well-known-key

This way a parachain (PVF and collator) can find all the parachains that
have an outbound channel to the given one. That allows in turn to find
all the inbound channels for the given para.

Having access to that allows the parachain to get the same information
as the hrmp_mqc_heads now provide.

* Rename `relay_storage_root` to `relay_parent_storage_root`

How to run this collator

First start two validators that will run for the relay chain:

cargo run --features=real-overseer --release -- -d alice --chain rococo-local --validator --alice --port 50551
cargo run --features=real-overseer --release -- -d bob --chain rococo-local --validator --bob --port 50552

Next start the collator that will collate for the adder parachain:

cargo run --features=real-overseer --release -p test-parachain-adder-collator -- --tmp --chain rococo-local --port 50553

The last step is to register the parachain using polkadot-js. The parachain id is 100. The genesis state and the validation code are printed at startup by the collator.

To do this automatically, run scripts/adder-collator.sh.
