Crate ink_prelude

Data structures to operate on contract memory during contract execution.

These definitions are useful since we are operating in a no_std environment and should be used by all ink! crates instead of directly using std or alloc crates. If needed we shall instead enhance the exposed types here.

The ink_prelude crate guarantees a stable interface between std and no_std mode.
