Summary: X-link: facebook/react-native#48404 ## Changelog: [Internal] - This popped up when profiling some heavy UI performance, calling `fmod` operation in Yoga's `roundLayoutResultsToPixelGrid` in `PixelGrid.cpp` can be expensive, furthermore it turns that some of the calls were redundant. This replaces the duplicate calls to fmod with an equivalent single round operation, which for clang compiler on Windows bring the code in question from ~50 instructions (including 4 call instructions to the fmod function) down to ~30 instructions (without any external calls), and the layout operation being **~1% more efficient** for the particular benchmark I was looking into.
