The Chrome OS-specific code has multiple function parameters that are
not used. This results in compilation warnings. Fix them with
[[maybe_unused]].

Commit 7d7879833812 ("android: mm: cros: Handle buffer registration
failure") mistakenly tried to initialize the CameraBuffer::Private
registered member variable instead of registered_. This reults in a
compilation failure. Fix it.

cros::CameraBufferManager::Register() fails if a buffer handle
is invalid. We should mark CameraBuffer as invalid on the failure
of Register().
While the cros::CameraBufferManager Unlock() and Deregister() functions
should be able to handle buffers that haven't been locked and
registered, this isn't an API guarantee, and errors will be logged.
Avoid this by skipping unlocking and unregistration of buffers that
haven't been locked or registered.

Introduce the CameraBuffer backend for the Chromium OS operating system
and the associated meson option.
The Chromium OS CameraBuffer implementation uses the
cros::CameraBufferManager class to perform mapping of 1 plane and multiplane
buffers and to retrieve size information.
