Call __makeNative on children before __getNativeTag (facebook#46524)

Summary:
Pull Request resolved: facebook#46524

There's an interesting behavior in Animated where we effectively perform an O(N + M) traversal of the Animated graph, calling `__makeNative` on each "input", which in turn tends to call `__makeNative` on each "output" (so we revisit the current node M times when calling `__makeNative` on the M inputs). In practice, the behavior is still O(N), because M is small and finite (most Animated nodes have 1 or 2 inputs).

All that said, some platforms (e.g., react-native-windows) rely on this revisiting behavior, where on the first visit, we recurse the node to its inputs, and on the subsequent visit, we update the `_platformConfig` value without recursion (see facebook#32736 for the original change adding platformConfig).

A recent change to AnimatedWithChildren (facebook#46286) eagerly invokes `__getNativeTag` on AnimatedWithChildren in the initial recursion step, which forces materialization of the NativeAnimated node *before* it's `_platformConfig` is set.

There is certainly some refactoring that needs to be done to improve all this, but for now, this change reverts to delay the call to `__getNativeTag` until after at least one `__makeNative` occurs on an input.
