…torage_item` macro to generate implementation of all traits and use a right storage types for `StorageMapping` and `StorageValue`.

Erc20 and Erc1155 works with a new storage. The size reduced ~550 bytes

Removed all lazy stuff except `StorageMapping` and `StorageValue`. Later I will rename `StorageMapping` into `Mapping`.
Removed `AtomicStatus` trait. Instead of it added `is_atomic!` macro that returns true if the object implements `AtomicGuard<true>`. It solves the problem when the struct contains generics. Now if the generic is marked as `AtomicGuard<true>` then the struct is atomic too, else it is not atomic.
Implemented `#[ink_lang::storage_item]` for structs, enums, and unions.
Started cleaning of the `SpreadLayout` and other stuff. The dispatching codegen already works without it.

…ng` are not atomic

Created derives for a new traits.
Added tests for derive.
Added experimental `StorageType2` and auto-selecting of the storage key.
Updated `storage_item` to be configurable and allow disabling auto derive for manual implementation.

Added `OnCallInitializer` with `pull_or_init!` for upgradeable case.
Renamed `StorageMapping` -> `Mapping`.
Added some comments adn updated tests.

Fixed tests. Added tests for `StorageType`. Updated comments.
Renamed `AutomationStorageType` into `AutoStorageType`

Added comments.

…l names that are used during the calculation of the storage key. The updated key calculation for tuples.

Introduced `StorageKeyComposer` to manage all rules for storage creation.
Used a `SHA2` instead of `Blake2b` to calculate the storage key hash. It is because `SHA2` supports const calculation. It is required for tuples.
Implemented UI tests for `#[ink_lang::storage_item]` and fixes bugs.
