Make Google Places package self-contained

[AdamEssenmacher]

Summary

• publish AdamE.Google.iOS.Places 7.4.0.3 with the Google Places XCFramework embedded in the NuGet package
• remove consumer-time Xamarin.Build.Download usage while preserving the 59-file root resource bundle for direct and transitive consumers
• add deterministic package-structure and isolated offline-build validation to the dedicated macOS 26 / Xcode 26.6 workflow

No managed public API, package ID, target framework, or minimum OS changes are introduced.

Validation

• packed 7.4.0.3 from a clean worktree with no existing externals, exercising the public Google SDK download
• verified package identity, both XCFramework slices and architectures, native metadata, exact bundle contents, MSBuild assets, and complete XBD removal
• built direct and transitive Places consumers; both linked the native symbol and received all 59 resources
• built successfully with network blocked, isolated NuGet caches, and an empty isolated XamarinBuildDownload directory
• confirmed the previous 7.4.0.2 XBD package fails the same offline proof
• passed all five Places simulator runtime cases
• packed SignIn 9.0.0 and passed both reusable consumer shapes as a regression smoke test
