This commit splits the old RTCCameraVideoCaptureTests into two;
RTCCameraVideoCaptureTests for tests using "setup", and

This cl/ attempts to fix (rather) rare crashes in
OnNetworkConnected_n by loosening the assumptions
that a network handle will keep it's network name.
With this cl/ it is possible that a NetworkHandle
can call OnNetworkConnected_n with one interface name
and then directly afterwards call it with another (
w/o an OnNetworkDisconnected_n inbetween).
This is the only scenario in which I could see the previous
crash occurring.
i.e
OnNetworkConnected(handle, "some-if-name")
OnNetworkConnected(handle, "some-other-name")
- previously this caused crash,
- now this is treated as if there was an OnNetworkDisconnected(handle) in between.
---
Also 1: shamelessly copy TYPE_MOBILE_DUN & TYPE_MOBILE_HIPRI from chromium: 87987f0e76
Also 2: Modify testcase not to use real interface names, so I can ran them on personal test phone w/o the real networks interfering.

AndroidNetworkMonitor::SetNetworkInfos assumes this method is called
only once, but unittests calls it twice.
One is called by the startMonitoring Java method, and the other is
called by each test.
Because of this, these tests will not succeed if dcheck_always_on is true.
To solve this problem, use OnNetworkConnected_n
instead of SetNetworkInfos in each test.

As the synchronous version only posts a task to recreate the encoder
later, it is not possible to catch errors and state changes that
could appear then.
The asynchronous version of SetParameters() aims to solve this by
providing a callback to wait for the completion of the encoder
reconfiguration, allowing any error to be propagate and subsequent
getParameters() call to have up to date information.
