…meter This lifts the check for the feature flag up into the `importParameterType` from `importType` and means that completion handler type for `async` variant is no longer gains `@Sendable` attribute. (cherry picked from commit 74471e8)
…r global actor isolated functions Functions that are isolated to a global actor don't have completion handlers imported as `@Sendable`. Main actor isolated functions with completion handlers that are always called on the main actor is a very common Objective-C pattern, and this carve out will eliminate false positive warnings in the cases where the main actor annotation is missing on the completion handler parameter. Resolves: rdar://149811049 (cherry picked from commit ab227b4)

Cherry-pick of #82085
Explanation:
Functions that are isolated to a global actor don't have completion
handlers imported as
@Sendable. Main actor isolated functions withcompletion handlers that are always called on the main actor is a
very common Objective-C pattern, and this carve out will eliminate
false positive warnings in the cases where the main actor annotation
is missing on the completion handler parameter.
