This PR fixes a few xrsimulator-arm64 lit failures:
* `test/lit.cfg`: The `FUTURE_VERSION` dict was missing `'xros'`, so
`%target-future-triple` collapsed to a versionless
`arm64-apple-xros-simulator` (pinned to the visionOS 1.0 deployment
floor) instead of the intended `...99.99...`.
* `utils/availability-macros.def`: the `SwiftStdlib 9999` entries had no
visionOS row, so the compiler derived visionOS availability from iOS
(`iOS 13.0 → visionOS 13.0`, etc.), producing unreachable version
requirements at the visionOS 1.0 deployment target.
* `Frontend/ast-dump-json-no-crash.swift` — the hand-authored
`@available(iOS, introduced: 14.0)` was flagged unavailable on visionOS
via iOS-derivation. Add an explicit visionOS 1.0 introduction.
* `IRGen/coroutine_accessors_backdeploy_async_56.swift` — visionOS
enters `RuntimeVersions.def` at 5.10/1.0, so Swift 5.7 is
always-available and the pre-5.7 back-deploy layout is never emitted.
`UNSUPPORTED: OS=xros`.
* `ModuleInterface/assoc_type_inference_tvos.swift` — the clang-importer
SDK does not contain SDKSettings.json, which is required for
availability derivation for visionOS. Marking as unsupported until that
is fixed.
*
`Concurrency/Runtime/{nonisolated_inherits_isolation,unspecified_is_main_actor}.swift`
— both `@_silgen_name("dispatch_assert_queue")` against a bare C symbol
that is hidden on visionOS 1.0 (only `$V2` is exported). `UNSUPPORTED:
OS=xros`.
* `TBD/multimodule-implied-objc.swift` — drop stale `XFAIL: OS=xros`
from the original "Introduce VisionOS Platform" bootstrap; the test now
passes.
