[native] [1/40] RN 0.70: Update React Native patchfile

Summary:
Our current patchfile has three patches: https://www.notion.so/commapp/React-Native-0-66-patchfile-a24a52cbf10a408e96a43822facfd5d7

The new patchfile only has one: https://www.notion.so/commapp/React-Native-0-70-patchfile-e54796687eb2449585e3076e2abf5ee2

The project.pbxproj instability fix was merged upstream, and the Folly build hacks appear to no longer be necessary (presumably because all the files we need are now included in the default build)

Depends on D5894

Test Plan: Tested along with whole stack: test plan
