Remove without_storage_info from the XCMP queue pallet. Part of #323

Changes:

  • Limit the number of channels that can be suspended at the same time.
  • Limit the number of channels that can have messages or signals pending at the same time.

A No-OP migration is put in place to ensure that all BoundedVecs still decode and not truncate after upgrade. The storage version is thereby bumped to 4 to have our tooling remind us to deploy that migration.

Implementation looks good and the intentions of this PR are clear, just a few questions about errors and tests.

Reverts #2302. 🤦‍♂️ should have checked the
migration CI first.

We either need to reduce the `max_message_size` for the open HRMP
channels on the failing chains or increase the `PageSize` of the XCMP
queue.
Both would be fine on a test-net, but i assume this will also fail
before the next SP runtime upgrade so first need to think what best to
do.
AFAIK its not possible currently to change the `max_message_size` of an
open HRMP channel.

Re-applying #2302 after increasing the `MaxPageSize`.  

Remove `without_storage_info` from the XCMP queue pallet. Part of
#323

Changes:
- Limit the number of messages and signals a HRMP channel can have at
most.
- Limit the number of HRML channels.

A No-OP migration is put in place to ensure that all `BoundedVec`s still
decode and not truncate after upgrade. The storage version is thereby
bumped to 5 to have our tooling remind us to deploy that migration.

## Integration

If you see this error in your try-runtime-cli:  
```pre
Max message size for channel is too large. This means that the V5 migration can be front-run and an
attacker could place a large message just right before the migration to make other messages un-decodable.
Please either increase `MaxPageSize` or decrease the `max_message_size` for this channel. Channel max:
102400, MaxPageSize: 65535
```

Then increase the `MaxPageSize` of the `cumulus_pallet_xcmp_queue` to
something like this:
```rust
type MaxPageSize = ConstU32<{ 103 * 1024 }>;
```

There is currently no easy way for on-chain governance to adjust the
HRMP max message size of all channels, but it could be done:
#3145.
