This moves this responsibility from the ResourceAdaptaitonProcessor
to the VideoStreamAdapter. A new interface for listening to adaptation
changes was added, and the ResourceAdaptationProcessor now listens on
the VideoStreamAdapter for those changes.
This means that going forward,
1. We can do adaptations outside of resource limitations, like setting
prior adaptations on a resource like initial frame dropper is designed
to.
2. Adaptations can be on a different queue than the
ResourceAdaptaitonProcessor's queue since updates are pushed through
the listener.

A more detailed explaination is in the bug, but this changes
the way that adaptation happens when multiple resources are
limited. Only the one that is most limited can trigger an
adaptation up. If multiple resources are most limited both
need to underuse to adapt up.
Some of the changes in this patch to make it all work:
* VideoStreamEncoder unittests that did not reflect this
new behaviour have been changed.
* PeekNextRestrictions returns the adaptation counters as
well as the restrictions.
* Adaptation statstics have changed so that when adapting
up all resources are tagged as triggering the adaptation.
Additionally the statistics for the current adaptation is
now the total number of adaptations per reason, rather then
the number of adaptations due to that reason.
* PreventAdaptUpDueToActiveCounts is removed as most limited
resource is a strong implementation of that.

The ResourceListenerResponse was used to make the QualityScaler
not clear QP samples and instead increase its frequency of checking for
QP under certain circumstances, see enum description:
https://webrtc.googlesource.com/src.git/+/c70b1028d47c1aee4892545190cd66e97d09cd55/call/adaptation/resource.h#33
Because the QualityScaler depends on whether and how adaptation
happened it should listen to adaptation happening.
This CL moves the logic that was previously in VideoStreamAdapter closer
to the QualityScaler: QualityScalerResource::OnAdaptationApplied().
This would allow the VideoStreamAdapter to operate on a separate task
queue in the future, with no dependencies on any stream-specific
resources that might operate on other task queues.

By pushing VideoAdaptationCounters updates on VideoSourceRestrictions
changes, alongside the Resource* that triggered the adaptation, we are
able to update |active_counts_| without an explicit dependency on the
VideoStreamAdapter. This allows a future CL to split up "processor"
logic from "video stream encoder resource and active counts" logic,
which will ultimately be necessary in order to do processing on a
"processing queue" and encoder and stats logic on the "encoder queue".
If the restrictions got cleared by an API call
(ResetVideoSourceRestrictions() or SetDegradationPreference()) we pass
null as the "reason_resource". This allows is to clear the
active_counts_, and the code that invokes
OnVideoSourceRestrictionsUpdated() does not have to be aware of
active_counts_ (needed to split the processor module in two).
