alsa_sound: Allow SPEAKER_DUAL_MIC_* UCMs with USES_FLUENCE_INCALL

Enables SND_USE_CASE_DEV_SPEAKER_DUAL_MIC_* UCMs when using speakerphone
with USES_FLUENCE_INCALL defined.  This allows devices to use different
DMIC settings for earpiece and speakerphone modes.

Devices that wish to retain the old behavior should clone the DUAL_MIC_*
UCMs for SPEAKER_DUAL_MIC_*.
alsa_sound: Add missing assignment of acdb_handle, fixes in-call volume

Assigns AudioHardwareALSA::mUcMgr->acdb_handle to mAcdbHandle, which is
missing in the port of dynamic library loading from the AOSP/mako HAL
(I04d5e7b96611572a7758c610ebdf0fd00e8346aa).

Restores acdb_send_voice_cal and acdb_send_audio_cal calls, which among
other things, are required for in-call volume adjustment to function.
