[Chromecast] Refactor UserAgent
1) Move the GetUserAgent() into its own files. 2) Remove
unused |user_agent| in GCMDriverDesktop to reduce confusion.
Merge-With: eureka-internal/631073
Bug: b/192098277, b/191670403
Test: Log the user agent and verify it's the expected value. This CL
also passes internal CQ.
