Add inverted lags index to simplify the loop in
`FindBestPitchPeriod48kHz()`. Instead of looping over 294 items,
only loop over the relevant ones (up to 10) by keeping track of
the relevant indexes.
The benchmark has shown a slight improvement (about +6x).
Benchmarked as follows:
```
out/release/modules_unittests \
--gtest_filter=*RnnVadTest.DISABLED_RnnVadPerformance* \
--gtest_also_run_disabled_tests --logs

`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

for which the tolerance has been slightly increased. Note that the pitch
estimation is still bit-exact.

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%.

1. the type for (inverted) lags and pitch periods changed from
size_t to int to reduce the chance of bugs with pitch period
manipulations
2. CheckLowerPitchPeriodsAndComputePitchGain() is optimized by
replacing an unnecessary if statement inside the loop with the
predetermined number of loops

`gn format` recently [1] changed its formatting behavior
for deps, source, and a few other elements when they
are assigned (with =) single-element lists to be consistent
with the formatting of updates (with +=) with single-element.
Now that we've rolled in a GN binary with the change,
reformat all files so that people don't get presubmit
warnings due to this.
CL generated with:
$ git ls-files | grep BUILD.gn | xargs gn format
$ gn format build_overrides/build.gni
$ gn format build_overrides/gtest.gni
$ gn format modules/audio_coding/audio_coding.gni
$ gn format webrtc.gni
$ gn format .gn
Plus a few manual changes to add exceptions for
"public_deps" (after changing these lines the presubmit
started to complain).

This CL adds the GRU weights memory layout optimization with which it
will be easier to add SSE2 code in a follow up CL. The new memory
layout also improves the performance of the unoptimized code.
This CL also includes a bug fix in the GRU layer input validation.
It was a silent bug since the GRU layer of the RNN VAD has the same
input and output size. This was caught by changing memory layout of
the recurrent weights. The unit test has been adapted by removing the
unused recurrent weights (the expected result does not change).

This CL adds the SSE2 optimized implementation for fully connected
(FC) layers. The change includes a weights re-alignment op done once
at construction time. It is required in order to optimize the load op
to fill 128 bit registers.
This CL also includes unit test adaptations and a benchmark test
(disabled by default).

Static libraries don't guarantee that an exported symbol gets linked
into a shared library (and in order to support Chromium's component
build mode, WebRTC needs to be linked as a shared library).
Source sets always pass all the object files to the linker.
On the flip side, source_sets link more object files in release builds
and to avoid this, this CL introduces a the GN template "rtc_library" that
expands to static_library during release builds and to source_set during
component builds.

This CL refactors the computation of band energy and spectral
cross-correlation coefficients by moving and optimizing
the code from ComputeBandCoefficients, ComputeBandEnergies and
ComputeSpectralCrossCorrelation into a single class (named
BandFeaturesExtractor).
This change will also help replacing FFT library in the RNN VAD.

The FFT output buffers sizes in SpectralFeaturesExtractor have been reduced
from N to N/2+1, where N is the audio frame size. This is required since
ComputeBandEnergies() currently calls ComputeBandCoefficients() indicating
a higher value for max_freq_bin_index, hence polluting the higher bands with
unwanted energy (coming from the symmetric conjugate copy of the Fourier
coefficients).

The pitch gain type in ComputePitchGainThreshold() is wrong
(size_t instead of float).
The pitch period is an unsigned integer type, but it is safer to
switch to a signed type and add checks on the sign.
