XHarness changed naming of things in dotnet/xharness#400 and we just follow in the SDK

Adds the possibility to target real Apple devices and sign the applications before deploying them using XHarness.

The signing process requires certificates to be placed on each Helix machine in a KeyChain and a provisioning profile from netcorenativeassets that is embedded into the application.

Integration testing will be coming soon

- The `OSX.1015.Amd64.Iphone.Open` queue is already populated with signing certificates and is ready to start signing
- The `OSX.1015.Amd64.AppleTV.Open` will be ready soon (#11675)

Resolves dotnet/core-eng#11678
