audio: Add IDevice::updateAudioPatch method
Add method 'updateAudioPatch' which should be used when
an existing patch needs to be updated with new routing.
Use of this method allows audio HAL to avoid disrupting
audio stream while changing routing.
Bug: 79248321
Test: atest VtsHalAudioV6_0TargetTest
Change-Id: I6c87f67fa4f2463ba9e8f0272a3232f5c9c55714
