[flutter_tools] PathNotFoundException in IOSCoreDeviceControl and Xcode Build temp directory cleanup #186954

Description

While PR #140842 successfully fixed PathNotFoundException in IOSCoreDeviceControl._listCoreDevices by introducing ErrorHandlingFileSystem.deleteIfExists, several other methods in the same class still rely on synchronous tempDirectory.deleteSync(recursive: true).

In high-frequency local testing environments, CI/CD systems, or during race conditions, these directories can be removed asynchronously (e.g., by background system cleanups or parallel tasks). When the finally block tries to clean up, it triggers an unchecked PathNotFoundException, leading to a crash.

Affected Code Locations

1. packages/flutter_tools/lib/src/ios/core_devices.dart at lines 527, 604, 652, and 747.
2. packages/flutter_tools/lib/src/ios/mac.dart at line 595.

Expected Behavior

The tool should utilize ErrorHandlingFileSystem.deleteIfExists to prevent throwing an uncaught PathNotFoundException if the directory was already deleted by the OS or a concurrent task during build cleanup.
