RNN VAD: Opus band spectral analysis refactoring

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.
