* sc-network-test::Peer: block push methods return hashes vec
This commit reworks the block generation/push methods in
sc-network-test::Peer.
Now methods are providing the vector of hashes that were built.
This allows to get rid of redundant `block_hash_from_id` call, as all
hashes are known just after being built.
Similar approach was taken in BeefyTestNet::generate_blocks_and_sync
method.
This PR is part of BlockId::Number refactoring analysis (paritytech/substrate#11292)

Instead of using a `u64` to represent the key we now use an `Arc<[u8]>`. This arc is also stored in

different storage roots. When the latest key usage is dropped in the lru, we also remove the key
from the `HashSet`.

* Introduce a "dynamic" block size limit for proposing
This adds support for using a dynamic block size limit per call to
`propose`. This is required for Cumulus/Parachains to always use stay in
the limits of the maximum allowed PoV size.
As described in the docs, the block limit is only checked in the process
of pushing transactions. As we normally do some other operations in
`on_finalize`, it can happen that the block size still grows when there
is some proof being collected (as we do for parachains). This means,
that the given block limit needs to be rather conservative on the actual
value and should not be the upper limit.
