Currently some RTPVideoHeaders are not filled with width and height
information, such as AV1. If we dump the stream with command line
“--force-fieldtrials=WebRTC-DecoderDataDumpDirectory/./”, and if
width and height are 0, it will crash soon.
This CL aims to avoid crashing when the |encoded_image._encodedWidth|
and |encoded_image._encodedHeight| are 0.

Important: This change does not in any way affect echo cancellation or standardized stats. The user audio experience is unchanged. Only non-standard stats are affected. Echo return loss metrics are unchanged. Residual echo likelihood {recent max} will no longer be computed by default.
Important: The echo detector is no longer enabled by default.
API change, PSA: https://groups.google.com/g/discuss-webrtc/c/mJV5cDysBDI/m/7PTPBjVHCgAJ
This CL removes the default usage of the residual echo detector in APM.
It can now only be used via injection and the helper function webrtc::CreateEchoDetector. See how the function audio_processing_unittest.cc:CreateApm() changed, for an example.
The echo detector implementation is marked poisonous, to avoid accidental dependencies.
Some cleanup is done:
- EchoDetector::PackRenderAudioBuffer is declared in one target but is defined in another target. It is not necessary to keep in the API. It is made an implementation detail, and the echo detector input is documented in the API.
- The internal state of APM is large and difficult to track. Submodule pointers that are set permanently on construction are now appropriately marked const.
Tested:
- existing + new unit tests
- audioproc_f is bitexact on a large number of aecdumps

There are cases for each of these getters where other code later takes
a reference to the passed object, meaning that these getters should be
returning a refptr. To prevent additional overhead from places that
simply access the getter to call additional methods without needing to
worry about taking a ref, the return values are converted to const refs.

Changing to an index for-loop (instead of using std::transform) allows the compiler (clang for x86 at least) to use 3 different registers in the loop rather than just 1, resulting in less pipeline stall (I'd assume). Interestingly, the compiler unrolls the loop(s) completely in both cases.
