Currently the trait StorageInfoTrait is implemented on the struct Pallet only when the attribute generate_storage_info is set.
But it can be handy to always generate the storage info even with partial information.

This PR makes storage implement a new trait PartialStorageInfoTrait which allows to return some partial information.
Then depending on whereas the attribute generate_storage_info is set, the Pallet will implement the StorageInfo using PartialStorageInfo or using StorageInfo

as a side note, the span should be improved in a follow up by #8850
the implementation should also be improved currently we allocate some small vec way too much. But we can do in a follow-up.

Looks good overall. I think one question that I would have now is the discoverability of storage items that were implemented with PartialStorageInfo. This is useful when I may later on want to visit those items and implement StorageInfo directly, but I guess this is more of a UI issue than anything else.

The partial storage info doesn't have the max_size bound. I think when the benchmarking process fail to get proper bound for max_size it will return an error or a warning saying that the storage doesn't have valid bound for PoV size computation.
