Remove NumericBitfield (facebook#1463)

Summary: X-link: facebook/react-native#41394 Pull Request resolved: facebook#1463 Now that are enums are unsigned, and we don't have BitfieldRef, we can convert the last remaining user of NumericBitfield to a plain old bitfield, for better readability (e.g. the default values), debugability, and less complexity. We also break a cycle which lets us properly group public vs private members. Differential Revision: D51159415 fbshipit-source-id: ca0639d47bc68f2d895e72aaaad1cbdb17294be2
