Improve contracts intrisics and remove wrapper function 1. Document the new intrinsics. 2. Make the intrinsics actually check the contract if enabled, and remove `contract::check_requires` function. 3. Use panic with no unwind in case contract is using to check for safety, we probably don't want to unwind. Following the same reasoning as UB checks.

Rename rustc_contract to contract This has now been approved as a language feature and no longer needs a `rustc_` prefix. Also change the `contracts` feature to be marked as incomplete and `contracts_internals` as internal.

#![feature(cfg_contract_checks, contracts_internals, core_intrinsics)]
Contracts core intrinsics. These are hooks to: 1. control whether contract checks are run 2. allow 3rd party tools to intercept and reintepret the results of running contracts.
