Define `SharedMemory` trait, implement it for `base::SharedMemory`, and
use it for `ShmStreamSource::new_stream()` so that we can pass on
`base::SharedMemory` without exposing `base` to libcras.
Note that we implement the trait for `base::SharedMemory` in `base`
crate instead of in `audio_streams`, which means `base` depends on
`audio_streams`, because `audio_streams` is available for non-crosvm
projects while `base` isn't.
The corresponding CRAS change is crrev.com/c/3251123.

By default, the memory of a protected VM is inaccessible to the host
and crosvm. Consequently, attempts to access guest memory are fatal and
must be avoided in order for the guest to run.
Mlock guest pages as they are faulted in for protected VMs, ensuring
that the host doesn't try to age or swap them out as a result of memory
pressure.
