Convert CastTransportHostFilter to be client of wake lock service.

Wake Lock is a Mojo interface that wraps PowerSaveBlocker. As part of the
creation of standalone Device Service, all browser-side clients of
PowerSaveBlocker should be converted to be clients of the Wake Lock Mojo
interface instead.

Remove the condition check on GetForProcess() in cast_transport_host_filter.

Remove the "if(ServiceManagerConnection::GetForProcess())", use the DCHECK()
instead to make sure the ServiceManagerConnection is always initialized in
production code.
