coral: device: add audio_effects.conf into vendor partition for aosp

Back port aosp/1542710 from master to aosp/android11-dev branch.

Aosp_flame also needs audio_effects.conf in vendor partition
to avoid selinux issue like what aosp_coral does.

Bug: 175658062
Bug: 201671438
Test: build passed and validate if there is audio_effects.conf
      in vendor partition
