  Regression: User-friendly name for the GPUProcess no longer gets set
https://bugs.webkit.org/show_bug.cgi?id=258600

Reviewed by Per Arne Vollan and Brent Fulgham.

Access to launch services has been blocked by the GPUProcess' sandbox. As a
result, the GPUProcess no longer gets a user-friendly name in Activity Monitor.

To address the issue, we now:
1. Have the UIProcess create a sandbox extension for launch services and send it
   to the GPUProcess to temporarily consume it during initialization
2. The GPUProcess, on initialization now consumes this extension
3. The GPUProcess checks in with Launch Services and sets the process name
4. The GPUProcess closes connections to launch services
5. The GPUProcess revokes the sandbox extension
