[Upstream] Import OCMock as a pod for RNTester on iOS

[Saadnajmi]

Summary

This is a change we have implemented in React Native macOS that I am now upstreaming: microsoft#1257

The library ocMock is currently imported as a checked in binary by RN-Tester to help run unit tests on iOS. That binary is only compiled for x86 on macOS, which meant we could not run tests on M1 / M2 Macs. Switching it so that we import from source as a pod should make maintenance easier for both iOS and macOS! :)

Original change notes:

Previously, we've been unable to test RNTester for macOS on an M1 machine. This is because we were using a framework that was prebuilt for Intel architecture, so the test components would fail to build.

The fix is to build OCMock from source directly instead of using a prebuilt version.

This is only necessary on macOS. The iOS version is already built for ARM architecture, as iOS devices have been running exclusively on ARM for a while now.

Hi @Saadnajmi, could you please resolve the conflicts on the Podfile.lock?
Also, please revert the changes to the RNTesterPods.xcodeproj/project.pbxproj as those changes should be applied by the cocoapod script and should not be checked in.

I'll then import the PR as it looks like that everything is green and it allow us to remove a bunch of files (which translates to less maintenance burden... so that's really good!)

Thank you so much for doing this!

Thanks for the catch! I didn't notice my pbxproj changes were unrelated, oof. The latest iteration should be clean :). Also thanks also goes to @amgleitman who did this change originally on our fork.
