Extract ProcessManager from ExtensionSystem.

This change removes ProcessManager's //chrome dependency because while
ProcessManager and ExtensionSystem are in //extensions the
ExtensionSystemFactory is in //chrome. This allows a service in
//extensions to declare a dependency on the ProcessManager's factory
directly.

Most of this patch is changing,
extensions::ExtensionSystem::Get(profile_)->process_manager() to, extensions::ProcessManager::Get(profile_).
