react-native: Use number literals in TypeScript types for FileReader and XMLHttpRequest states

[eps1lon]

Summary

Mostly to improve compat in codebases where lib.dom.d.ts is loaded alongside RN. TS 5.0 updates to lib.dom.d.ts added number literals for these states as well so the abstract number type from RN was no longer compatible.

Forward-port of DefinitelyTyped/DefinitelyTyped#64144

Underlying flow types:

• https://github.com/facebook/react-native/blob/v0.71.1/Libraries/Blob/FileReader.js#L33-L35
• https://github.com/facebook/react-native/blob/v0.71.1/Libraries/Network/XMLHttpRequest.js#L54-L58

Changelog

[GENERAL] [CHANGED] - Use number literals in TypeScript types for FileReader and XMLHttpRequest states

Test Plan
