[Media Router] Fix URLRequestContext leak and race condition.

Remove usage of SystemURLRequestContextGetter which has led to several
issues including shutdown leak and test setup problems. This means 2
things:
- No more NetLog for DIAL and Cast sockets (for now. When we switch to
NetworkService we can reconsider adding back support depending on
our needs)
- DIAL device description / app info fetch now replaced with URLLoader
APIs that's part of network service.

The race condition issue caused by calling CMSSImpl::GetWeakPtr on two
different sequence is fixed by not using a WeakPtr by assuming
CMSSImpl outlives DialMSSImpl, which is true due to their ordering in
DualMediaSinkService. Also removed the PostTask trampoline by assuming
they both run on the same sequence.
