Let Opus increase complexity for low bitrates

This change adds code that lets Opus increase the complexity setting
at low bitrates (only relevant for mobile where the default complexity
is not already maximum). The feature is default off.

Also adding a performance test to make sure the complexity adaptation
has desired effect.
