Crate ink_primitives

Utilities in use by ink!.

These are kept separate from ink! core utilities to allow for more dynamic inter-crate dependencies. The main problem is that today Cargo manages crate features on a per-crate basis instead of a per-crate-target basis thus making dependencies from ink (or others) to ink_env or ink_storage impossible.

By introducing ink_primitives we have a way to share utility components between ink_env or ink_storage and other parts of the framework, like ink.
