bb1a28de3c RNN VAD: unit test code clean-up 
- test_utils.h/.cc simplified
- webrtc::rnnvad::test -> webrtc::rnnvad
- all unit test code inside the anonymous namespace
- names improved

253f8369bb AGC2 RNN VAD: safe SIMD optimizations scheme + AVX2 kill switch 
In preparation for adding AVX2 code, a safe scheme to support
different SIMD optimizations is added.

Safety features:
- AVX2 kill switch to stop using it even if supported by the
  architecture
- struct indicating the available CPU features propagated from
  AGC2 to each component; in this way
  - better control over the unit tests
  - no need to propagate individual kill switches but just
    set to false features that are turned off

Note that (i) this CL does not change the performance of the RNN VAD
and (ii) no AVX2 optimization is added yet.

f622ba725e AGC2 RNN VAD size_t -> int 
Motivation: read "On Unsigned Integers" section in
https://google.github.io/styleguide/cppguide.html#Integer_Types

Plus, improved readability by getting rid of a bunch of
`static_cast<int>`s.

2f1e6d4920 AGC2 RNN VAD: Polishing. 
- Code clean: exploiting the recently added ArrayView ctor for
  std::array
- Pitch search internal unit test: long const arrays moved to
  a resource file
- Minor changes

beb1d34729 AGC2 RNN VAD: Feature extraction. 
This CL finalizes the feature extraction part for the RNN VAD adding
a class that combines a high-pass filter, LP residual computation,
pitch estimation and spectral features extraction.

This CL also includes a minor refactoring of the pitch estimation
library.
