Audio HAL: Add new HAL for sound dose
The new HAL is running as part of the HIDL audio HAL process. It is
meant as a workaround for HAL implementors that can not switch to the
audio AIDL yet and need to certify with IEC62368-1 3rd edition or
EN50332-3. Note that this HAL will be deprecated in the future.
Test: atest VtsHalSoundDoseFactoryTargetTest & flash bluejay-userdebug
Bug: 257937004
