Modularization: Extract Tor into a separate module (#602)

* Extract Tor into a separate module

* Add Tor package as a dependency for iOS & macOS targets

* Move `tor-nolzma.xcframework` inside Tor

* Remove `libz` from Frameworks as its linked in Tor

* Remove stray `.gitkeep` from macOS target membership

* Fix missing import and access control for modularized Tor

- Add import Tor to NetworkActivationService
- Make TorManager.shutdownCompletely() public for external access

* Fix tor-nolzma.xcframework structure for Xcode builds

- Add missing Info.plist files to all framework slices
- Restructure macOS framework to use deep bundle format (Versions/)
- Keep iOS frameworks as shallow bundles (standard for iOS)

This fixes the Xcode build errors while maintaining SPM compatibility.

* Remove stale xcframework references from Xcode project

Xcode cleaned up old direct references to tor-nolzma.xcframework
since it's now managed internally by the Tor Swift package.
