Use Xcode 11.6.0 and CocoaPods 1.9.3 (facebook#28837)

Summary:
Pull Request resolved: facebook#28837

CocoaPods 1.9.3 is the version that is distributed by Circle CI to macOS machines alongside Xcode 11.6.0.

The upgrade to CocoaPods and Xcode is therefore tightly coupled due to our dependency on Circle for our open source CI.

With the upgrade to Xcode 11.6.0, we also bump our target OS to ensure iOS tests use an iOS Simulator that is part of the image.

Reference:
* Circle CI macOS Xcode 11.6.0 image manifest (new version): https://circle-macos-docs.s3.amazonaws.com/image-manifest/v3299/index.html
* Circle CI macOS Xcode 11.3.1 image manifest (previous version): https://circle-macos-docs.s3.amazonaws.com/image-manifest/v2244/index.html
