Summary:
This improves JS validations of the transform object and makes it a bit stricter (hence the breaking change). When moving transform objects parsing to native (#10658) the validations got out of sync a bit, this makes sure JS validations are the same or stricter than the native ones to make sure we get consistent errors across platforms.
See #12110 for an example of an error that now gets caught by JS validations.
Also added snapshot tests for the errors to make sure `processTransform` throws when passing invalid values. It only tests the validation since the object parsing is now done natively for iOS and Android.
**Test plan**
Test that there are no errors in UIExplorer
Run new unit tests
