Run CLANGFORMAT for FlipperKitTestUtils

Summary:
This diff runs CLANGFORMAT lint on FlipperKitTestUtils. I have added CLANGFORMAT as the lint engined for objc files in xplat/sonar. Right now the iOS folder is not formatted according to CLANGFORMAT.
Ran `arc lint -a --paths-cmd "find ./iOS/FlipperKitTestUtils -type f" --verbose`
