SwiftAsync: use runtime-provided flag for extended frame if back-deploying
Introduce a new command-line flag `-swift-async-fp={auto|always|never}`
that controls how code generation sets the Swift extended async frame
info bit. There are three possibilities:
* `auto`: the default, which determines how to set the bit based on
deployment target, either statically or dynamically via
`swift_async_extendedFramePointerFlags`.
* `always`: always set the bit statically, regardless of deployment
target.
* `never`: never set the bit, regardless of deployment target.
