Remove Fork of getNativeComponentAttributes.js

[chiaramooney]

Problem Description

Needed for fork getNativeComponentAttributes.js because its original file contents was producing a bunch of errors due to its usage of a deprecated comment getViewManagerConfig. I replaced these calls with the new API hasViewManagerConfig. This change should be upstreamed. The fork can be removed once the upstream PR is integrated.

Link to the integration where the error originated

#14724

@chiaramooney Can you assign to the right integration shadow so this gets tracked for the upstream PR?
