Add a TickTimer object to NetEqImpl

Add a TickTimer object to NetEqImpl

The TickTimer is incremented on each call to GetAudioInternal(). Other
than that, the new object is not used yet.

Also adding a unit test in NetEqImplTest to verify that the tick timer
is incremented in the call to NetEq::GetAudio.
