Fix support framework linkage for binary consumers

[Kyle-Ye]

Summary

• make OpenSwiftUICore the single owner of static support modules and AttributeGraph linkage
• distribute CoreGraphics, QuartzCore, Observation, and RenderBox support as dynamic frameworks
• link the C++ runtime from OpenSwiftUICore when using the Compute backend
• resolve local and Tuist-derived dependency projects consistently during XCFramework packaging
• consume the latest OpenCoreGraphics support-framework dependency fix

Motivation

Binary SwiftPM consumers could load duplicate support types or fail to locate runtime framework dependencies, preventing application and Preview hosts from launching. This keeps static AttributeGraph support owned by OpenSwiftUICore while distributing the remaining runtime support frameworks explicitly.

Validation

• release-equivalent Compute packaging produces all seven XCFrameworks for macOS, iOS Simulator, and iOS Device
• every generated XCFramework has the expected three platform slices
• the local binary-package Example builds successfully for the iOS Simulator

🤖 Augment PR Summary

Summary: Fixes binary-consumer linkage by making OpenSwiftUICore the single owner of static support modules and AttributeGraph linkage.

Changes:

• Moves shim/support linkage out of OpenSwiftUI and into OpenSwiftUICore to avoid duplicate runtime types for binary consumers.
• Adds conditional C++ runtime linkage (-lc++) for the Compute backend on Darwin platforms.
• Adjusts packaging product types to distribute CoreGraphics/QuartzCore/Observation/RenderBox support as dynamic frameworks, while keeping AttributeGraph shims static (and adds OpenObservationCxx as static).
• Improves XCFramework build scripting to consistently resolve dependency projects between local checkouts and Tuist-derived projects, and expands macro-reference cleanup for OpenObservation.
• Updates the OpenCoreGraphics support dependency revision to pick up the latest support-framework fix.

dependency_project_path echoes local_project unconditionally when OPENSWIFTUI_USE_LOCAL_DEPS=1; if the local checkout path is missing, the resulting xcodebuild failure can be hard to diagnose. Consider validating that the path exists (or emitting a targeted error) before returning it.

Severity: medium
