Concurrency: Make _Concurrency module interface parsable by older compilers.

Revert a few unnecessary changes have been made to the _Concurrency module
recently that make its swiftinterface un-parseable by older compilers that we
need to support.

- The `consume` keyword is not understood by older compilers, so including it
  in inlinable code is a problem. It has no actual effect on lifetimes where it
  was used, so just omit it.
