This change introduces a new compilation target platform to the Swift compiler - visionOS. - Changes to the compiler build infrastrucuture to support building compiler-adjacent artifacts and test suites for the new target. - Addition of the new platform kind definition. - Support for the new platform in language constructs such as compile-time availability annotations or runtime OS version queries. - Utilities to read out Darwin platform SDK info containing platform mapping data. - Utilities to support re-mapping availability annotations from iOS to visionOS (e.g. 'updateIntroducedPlatformForFallback', 'updateDeprecatedPlatformForFallback', 'updateObsoletedPlatformForFallback'). - Additional tests exercising platform-specific availability handling and availability re-mapping fallback code-path. - Changes to existing test suite to accomodate the new platform.
