Export basic types directly instead of vm-logic

[ilblackdragon]

Currently basic types like BlocmHeight used inside Bindgen but also client contracts need also import them from near-vm-logic
It's very confusing and adds extra dependency that can be misaligned (like right now with crate.io having 0.4.4 whereas Bindgen depended on 0.4.3).

Ideally Bindgen should just export these types itself and client contracts don't need to depend directly on near-vm-logic.

Moving to Backlog and assigning P2 since we will be cleaning up near-bindgen soon anyway.

Closing, only unit testing (non-wasm32) depends on nearcore crates.
