Pull Request Overview
This PR enables the CoreCLR interpreter by default on Apple mobile platforms (iOS, tvOS, macOS Catalyst) and transitions from static to dynamic linking for CoreCLR libraries in the AppleAppBuilder. This includes updating the build configuration, code signing logic for dynamic libraries, and ARM64 assembly constant offsets.
Key Changes:
- Enables the interpreter feature for Apple mobile platforms in the CoreCLR build system
- Switches from static linking (
shouldStaticLink = false) to dynamic linking for Apple mobile platforms - Updates code signing to handle dynamic libraries in iOS app bundles
- Corrects ARM64 assembly offsets for release builds on Unix
