Add `cocoapods-binary-cache` plugin

## Why

Currently, we are using Cocoapods with the iOS templates. It's better to have a plugin that helps to reduce the build time of Xcode projects that use CocoaPods by prebuilding pod frameworks and caching them in a remote repository to share across multiple machines.
