Summary: setStyleInputs batching API was added to reduce the number of jni calls and although it improved performance in yoga world but was not impactful in litho and is not used anywhere. Removing this saves around 500 bytes per architecture #Changelog: [Internal][Yoga] Removed unused code setStyleInputs batching API form Yoga Reviewed By: amir-shalem Differential Revision: D18036536 fbshipit-source-id: 7436b55dcd464dd9f9cc46406d4fd78d12babe55
