14273de88b Make ProcessThread be a TaskQueue implementation 
That would allow to switch components from relying on ProcessThreads to
relying on TaskQueue one by one, without introducing new threads.

8e998f17e0 Fixes stall in SimulatedProcessThread 
A previous refactoring introduced an issues in SimulatedProcessThread
causing stalls when task are posted. This CL fixes this and cleans up
the code to make it easier to see that it's correct.

6ce033a863 Moves ownership of time controller into NetworkEmulationManager. 
This makes it easier to maintain consistency between real time
and simulated time modes.

The RealTimeController is updated to use an explicit main thread,
this ensures that pending destruction tasks are run as the network
emulator goes out of scope.

86d053c2db Use source_sets in component builds and static_library in release builds. 
Static libraries don't guarantee that an exported symbol gets linked
into a shared library (and in order to support Chromium's component
build mode, WebRTC needs to be linked as a shared library).

Source sets always pass all the object files to the linker.

On the flip side, source_sets link more object files in release builds
and to avoid this, this CL introduces a the GN template "rtc_library" that
expands to static_library during release builds and to source_set during
component builds.

See: https://gn.googlesource.com/gn/+/master/docs/reference.md#func_source_set

317a1f09ed Use std::make_unique instead of absl::make_unique.
