AudioPolicy: several spatializer output management fixes
Apply several fixes for spatializer output management when
the spatializer can be attached to two hardware modules (for instance
the primary and Bluetooth hardware modules).
- in getSpatializerOutput() open the output with
openOutputWithProfileAndDevice() to properly create the duplicating
output if needed and handle dynamic audio profiles.
- in openOutputWithProfileAndDevice(), do not open a duplicating output
for outputs opened on the primary module.
- in closeOutput(), clear mSpatializerOutput if this is the output being
closed.
- Allow canBeSpatialized() to ignore config matching with opened mSpatializerOutput
when not required.
- Force multichannel mixer mask in SwAudioOutputDescriptor::open() when
opening a spatializer output and the mixer config is not specified.
Bug: 210803914
Test: spatializer over Bluetooth A2DP
