Add contract variable declarations
Contract variables can be declared in the `requires` clause and
can be referenced both in `requires` and `ensures`, subject to usual
borrow checking rules.

This allows any setup common to both the `requires` and `ensures`
clauses to only be done once.

Guard HIR lowered contracts with contract_checks
Refactor contract HIR lowering to ensure no contract code is
executed when contract-checks are disabled.

The call to contract_checks is moved to inside the lowered fn
body, and contract closures are built conditionally, ensuring
no side-effects present in contracts occur when those are disabled.
