devices: snd: Use PCM device client_type and stream_type for CRAS

Read PCM device parameters and set CRAS client's client type and stream
type. Fallback to the virtio snd device's client type and
CRAS_STREAM_TYPE_DEFAULT if not set.

Resize the PCM device config of the provided parameters to match the
number of PCM devices.

Also add unit test for the virtio-snd::new function which checks the
PCM device config resizing and the data that are derived from the
parameters.

crosvm - The ChromeOS Virtual Machine Monitor

crosvm is a virtual machine monitor (VMM) based on Linux’s KVM hypervisor, with a focus on simplicity, security, and speed. crosvm is intended to run Linux guests, originally as a security boundary for running native applications on the ChromeOS platform. Compared to QEMU, crosvm doesn’t emulate architectures or real hardware, instead concentrating on paravirtualized devices, such as the virtio standard.

crosvm is currently used to run Linux/Android guests on ChromeOS devices.
