[Bindings] Update multiple frameworks up to Xcode 27.0 Beta 5

Update bindings for every requested framework:

- Accessibility: add the cross-platform AX speech SSML attribute key.
- AuthenticationServices: expose the Platform SSO authorization-scope option on macOS.
- CoreImage: bind asynchronous RAW decoder resource downloads with progress reporting.
- CoreMedia: add human-readable metadata description and specification keys, including the strong dictionary projection.
- CoreTelephony: add the NotSupported cellular plan authorization status.
- ImageIO: expose the quality-prioritized image source option and test its dictionary serialization.
- NetworkExtension: remove the packet-tunnel IP-family API surface that is now visionOS-only, and suppress the intentional branch-base API removals.
- PassKit: add the PayPak, Maal, and Elcard payment networks.
- PhotosUI: add the iOS photo-search-suggestion initializer.
- ReplayKit: deprecate RPScreenRecorder in favor of ScreenCaptureKit on every supported platform.
- ThreadNetwork: update the credential-sharing selector and add nearby active-credential retrieval.
- UIKit: add sheet placement values and the preferred placement property with tvOS member exclusions.
- VideoToolbox: add low-latency super-resolution scale-factor and dimension capability APIs.

Compatibility and intentionally unchanged items:

- Preserve the shipped VideoToolbox GetSupportedScaleFactors nint[] API for the current ABI, while queuing the header-correct float[] shape under XAMCORE_5_0.
- Keep the five older CoreMedia metadata specification keys ignored because the broader metadata registry family remains intentionally unbound and those entries were outside the Beta 5 TODO scope.
- Keep NetworkExtension APICompat suppressions limited to branch-base comparisons; the withdrawn APIs never shipped in the stable 26.5 baseline.

Validation:

- Ran the mandatory initial make world, rebuilt with make world for every binding/API change, and ran a final make world after review fixes.
- Clean xtro generation and dotnet-classify passed with Sanity check passed; all 41 in-scope TODO files are resolved and removed.
- Clean Cecil tests passed: 112 passed, 4 skipped, 0 failed.
- Clean .NET app-size tests completed with 16 intentional skips under the beta-Xcode guard and 0 failures.
- Stable and origin/xcode27.0 APICompat comparisons passed for iOS, tvOS, macOS, and Mac Catalyst.
- ImageIO monotouch fixtures built and ran on all four platforms; Xcode 27 simulator runs succeeded and desktop hosts reported only expected OS-version skips.
- Introspection passed on iOS 27.0 (44/44), tvOS 27.0 (43/43), and macOS (32/32, 2 host-version skips).
- Mac Catalyst passed every non-constructor introspection fixture (36 passed, 4 expected ignored); the three constructor tests remain unexecutable in this headless environment because CoreLocationUI.CLLocationButton triggers the documented TCC privacy abort.
- GPT-5.6 Sol and Claude Opus 5 reviewed both the interpretations/proposals and the final diff/results at maximum reasoning; all substantive findings were resolved.
