`ComputeSlidingFrameSquareEnergies()` which computes the energy of a
sliding 20 ms frame in the pitch buffer has been switched from backward
to forward.
The benchmark has shown a slight improvement (about +6x).
This change is not bit exact but all the tolerance tests still pass
except for one single case in `RnnVadTest,PitchSearchWithinTolerance`
for which the tolerance has been slightly increased. Note that the pitch
estimation is still bit-exact.
Benchmarked as follows:

This CL brings a large improvement to the VAD by precomputing the
energy for the sliding frame `y` in the pitch buffer instead of
computing them twice in two different places. The realtime factor
has improved by about +16x.
There is room for additional improvement (TODOs added), but that will
be done in a follow up CL since the change won't be bit-exact and
careful testing is needed.

TL;DR this CL improves efficiency and includes several code
readability improvements mainly triggered by the comments to
patch set #10.
Highlights:
- Split `FindBestPitchPeriods()` into 12 and 24 kHz versions
to hard-code the input size and simplify the 24 kHz version
- Loop in `ComputePitchPeriod48kHz()` (new name for
`RefinePitchPeriod48kHz()`) removed since the lags for which
we need to compute the auto correlation are a few
- `ComputePitchGainThreshold()` was only used in unit tests; it's been
moved into the anon ns and the test removed
This CL makes `ComputePitchPeriod48kHz()` is about 10% faster (measured
with https://webrtc-review.googlesource.com/c/src/+/191320/4/modules/audio_processing/agc2/rnn_vad/pitch_search_internal_unittest.cc).
The realtime factor has improved by about +14%.

This change makes the transparent mode classifier consider filter
convergence also for microphone signals with very low volume. This is
in order to prevent entering transparent mode when there is low, but
audible, echo.
Furthermore, the suppression gain during transparent mode is restored
to avoid leaks when the echo is too low to be reliably detected by
filter convergence.

Make the digital adaptive gain applier more robust to VAD false
positives. Achieved by allowing a gain increase only if enough adjacent
speech frames are observed.
Tested:
- Bit-exactness verified with audioproc_f
- If `kDefaultDigitalGainApplierAdjacentSpeechFramesThreshold` == 2
then not bit-exact

This reverts commit 2978abb88c49362e296bdce3cb662f6255b17083.
Reason for revert: Breaks ApmTest.Process.
After trying to enable AVX2, we increased the amount of error
we tolerate (kFloatNear) and this CL introduced a regression which
makes the test fail after we reverted the enabling of AVX2 (restoring
the old tolerance).
With this CL:
../../modules/audio_processing/audio_processing_unittest.cc:1779: Failure
The difference between test->rms_dbfs_average() and rms_dbfs_average is 0.00142669677734375, which exceeds kFloatNear, where
test->rms_dbfs_average() evaluates to 52.907142639160156,
rms_dbfs_average evaluates to 52.905715942382812, and
kFloatNear evaluates to 0.00050000000000000001.

This CL was written in preparation for the next CL in the chain and
it contains the following changes:
- SignalWithLevels -> AdaptiveDigitalGainApplier::FrameInfo
- Frame view removed from AdaptiveDigitalGainApplier::FrameInfo
- AdaptiveDigitalGainApplier::Process now gets side info as const& to
avoid unnecessary copies
- AdaptiveAgc::Process: `last_audio_level` renamed to `limiter_envelope`
to better reflect what that actually is
- Missing class/method docstrings added

This is the last CL needed to add a new `AdaptiveModeLevelEstimator`
feature that makes AGC2 more robus to VAD mistakes: the level estimator
discards estimation updates when too few consecutive speech frames are
observed.
This CL adds a second state property to hold temporary updates and a
counter for consecutive speech frames. When enough speech frames are
observed, the reliable state is updated; otherwise, the temporary state
is discarded.
The default for `AdaptiveModeLevelEstimator::min_consecutive_speech_frames_`
is 1, which means that the new feature is disabled.
Tested:
- Bit-exactness verified with audioproc_f
- Not bit-exact if `min_consecutive_speech_frames_` set to 10

This is the second CL needed to add a new `AdaptiveModeLevelEstimator`
feature that makes AGC2 more robus to VAD mistakes: the level estimator
discards estimation updates when too few consecutive speech frames are
observed.
In this CL, the `SaturationProtector` class has been replaced by a
struct that define the state and two functions to change it.
This is done in order to use the saturation protector state in
`AdaptiveModeLevelEstimator::State` and will allow to add a
temporary state in `AdaptiveModeLevelEstimator` (see the child CL).
