[tracking] remove without_storage_info for pallets migrating to AH

[muharem]

The pallets with #[pallet::without_storage_info] attribute or storage items with #[pallet::unbounded] attribute do not require a stored types to be bounded by the size. This simply means that those types may not implement the MaxEncodedLen trait.

The size bound required for estimation POV for a given extrinsic in advance (before executing it) and making sure a given extrinsic can fin in the a block. For the Parachains the POV estimation is mandatory and all pallets that will be setup on Asset Hub must have size bounds on the stored types, hence have no attributes like #[pallet::without_storage_info] and [pallet::unbounded].

There generally two use cases:

1. Sized types that can derive impl of MaxEncodedLen with #[derive(MaxEncodedLen)];
2. Unbounded type like Vec which must be migrated to BoundedVec<Member, Config::MaxMembers>.

The list of pallets with the attributes and migrating to AH:
