Subject: libcamera: Rename V4L2Device to V4L2VideoDevice
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

In preparation of creating a new V4L2Device base class, rename
V4L2Device to V4L2VideoDevice.

This is a project wide rename without any intended functional change.
