* FrameCombiner is simpler. No additional channel pointers for buffers.
* Improve consistency in using views in downstream classes.
* Deprecate older methods (some have upstream dependencies).
* Use samples per channel instead of sample rate where the former is
really what's needed.

This simplifies the following steps:
* FrameCombiner infers the sample rate from channel size
* Sends the inferred sample rate to FixedDigitalLevelEstimator
and Limiter.
* Those classes then convert the sample rate to channel size.
Along the way perform checks that the derived channel size value
is a legal value (which has already been done by FrameCombiner).
To:
* FrameCombiner sends channel size to FixedDigitalLevelEstimator and
Limiter.

carry audio properties. Also, now allocating FrameCombiner allocates

Start introducing ArrayView to AudioFrame and code that flows down
from there. In this first step:
* Add `data_view()` that returns a read-only ArrayView for the
audio buffer. When AudioFrame is not initialized however, data_view()
will return a nullptr whereas the current data() method never returns
nullptr.
* Add `mutable_data()` that requires two arguments for properly setting
the samples per channel and number of channels that's required for
accurately reserving the returned mutable ArrayView.
A notable behavior change is that if the requested number of channels
is larger than supported or the calculated buffer size is too large,
the function will trigger a check.
* Add TODOs for following work.

Removes the top 3 filtering based on frame energy. This behaviour is
unexpected for many application developers and the platform should not
have such arbitrary limitations. Developers can still implement top-N
filtering using WebAudio or an SFU (recommended to increase
scalability).
Performance is not really a concern in this case since decoders on all
receive streams are called regardless if they are mixed or not
(assuming packets are received).
This also fixes glitches caused by the current implementation since
sources are not ramped out.

This makes it a bit more clear that values of member variables of
SourceFrame are never directly changed and that doing so is not an
intentional part of the design. Also made use of `SourceFrame` vs
`const SourceFrame` more consistent since the audio frame of a
`const SourceFrame` was being modified in some places.
Accessing the embedded AudioFrame can be done via the const
audio_frame() accessor or via the mutable_audio_frame() accessor when
modifying the frame is needed. This helps with clarifying later on
when downstream code paths such as ones that access the `packet_infos_`
data, can know that it won't be modified for the rest of the frame's
lifetime (thus avoiding having to make copies).

This adds the histogram WebRTC.Audio.AudioMixer.NewHighestSourceCount
which logs the highest number of sources an AudioMixer has had. The
statistic is logged whenever the highest number of sources increases.
This allows us to differentiate the statistic to see how many times
the mixer has had a certain maximum number of sources.

We need to be able build chromium with rtc_include_tests = true. It
reveals a lot of targets that are not compatible with chromium but
aren't marked so.
`rtc_include_tests=true` has been considered a way to disable targets for the Chromium build, causing an overload on rtc_include_tests while the meaning of the two GN args (rtc_include_tests and build_with_chromium) should be kept separated.
