Require HW AV sync flag match for compatible output IOProfile
Previously, Audio HAL implementers need all HW A/V sync profiles
declared after non HW A/V sync profiles in their audio policy
configurations, otherwise a HW A/V sync profile match could be
found for a non HW A/V sync (e.g. direct only) request, the
Audio HAL output stream would be opened with the HW A/V sync
flag, and Audio HALs typically fail to process the stream as
they are setup to parse in-band HW A/V sync headers (even if
they don't receive keyStreamHwAvSync AudioParameter).
Test: atest audiopolicy_tests
AudioPolicyManagerTVTest#MatchOutputNoHwAvSync fails w/o IOProfile change,
passes with the change.
