media/gpu/v4l2: rename V4L2VP9Accelerator to V4L2LegacyVP9Accelerator

Our current VP9 accelerator uses a Chromium-only, non mainline ABI to
communicate with the kernel. As we are about to introduce the
upstream-based ABI, and the corresponding VP9 accelerator, rename our
older one to "legacy" following the model already followed for H.264 and
VP8.

BUG=b:161415741
TEST=Chromium builds for arm-generic.
