Summary: Concolidate the creation of the "update payload" into
ReactNativeAttributePayload which now has a create
and a diff version. The create version can be used by
both mountComponent and setNativeProps. This means that
diffRawProperties moves into ReactNativeAttributePayload.
Instead of storing previousFlattenedStyle as memoized
state in the component tree, I recalculate it every
time. This allows better use of the generational GC.
However, it is still probably a fairly expensive
technique so I will follow it up with a diff that
walks both nested array trees to do the diffing in a
follow up.
This is the first diff of several steps.
