[Concurrency] Define the availability macro SwiftStdlib 5.5

xymus · xymus · commit 0233b94dcd02 · 2021-05-04T09:30:54.000-07:00
The use of an availability macro will make it easier to update those
versions to the marketing versions when they are announced. Plus
internal branches can redefine only the macro for customized
availability.
