policy_hal: add bitrate restriction for wma/wma_pro/wma_lossless

HW decoded wma is wrong when bit rate of wma files is over specific
threshold, and noise can be heard when playing high bitrate wma files.

Check the bitrate of wma files when checking offload support, when
bit rate is too high, wma cannot be offloaded.
