cfed6b22 - [Concurrency] Provide an alternative implementation when "async { }" is unusable

[Concurrency] Provide an alternative implementation when "async { }" is unusable There exist Swift builds that support `Sendable` but not the attributes used on `async`. Make sure that have an implementation of `_runTaskForBridgedAsyncMethod` that does something. Fixes rdar://77637570. (cherry picked from commit 9788cc2cf4a6c6142173dd034d0bec534642163f)
