Audio VTS: HAL can support more than the native sampling rates

getSupportedSampleRate should return the native sampling rates,
(IE. the sampling rates that can be played without resampling)
but other sampling rates can be supported by the HAL.

The test was too strict as it was failing if HALs were supporting more
sample rates than there native (optimized) ones.

For example, a HAL might have its best performance (no resampling)
on 48kHz but still support 16kHz through resampling.

Note: getSupportedSampleRate might be renamed to getNativeSampleRate in
the next major HAL revision to avoid ambiguity.

Test: vts-tradefed run commandAndExit vts --module VtsHalAudioV2_0Target -t CheckConfig.audioPolicyConfigurationValidation
