Remove setup-xcode-build-cache action (#53177)

Summary:
Pull Request resolved: #53177

This action is used only when running tests for RNTester. Now that we are using prebuilds, this is a liability, because Cocoapods and Xcode would not update the binary if a new one is provided.

With prebuild, this caching does not provide a lot of benefits, so we can remove it.
