This is a reland of commit 213f9fe8a7.
In light of the upcoming VAAPI video decoder backend, add a VAAPI
wrapper crate that exposes a safe Rust API for a subset of the VAAPI C
code. This crate will be called from the VAAPI video decoder backend in
order to decode frames.

The virtio video decoder device is currently only available under very
drastic conditions: a build linked against libvda (a ChromeOS-only
library that needs the cros chroot to be built and linked against), and
a ChromeOS-flavored Chrome instance running alongside crosvm, so the
browser can provide the video decoding service through Mojo.
This makes the decoder device very difficult to develop on for
non-Chromies, and also for Chromies actually since they will always need
a DUT to test it on.
This patch introduces an alternative decoder backend based on
ffmpeg's libraries that performs decoding on the host's CPU. It supports both
guest pages and virtio objects as target, and can be considered a
reliable and predictable way to test the decoder in any environment.
We introduce our own ffmpeg bindings after a quick state of the art
revealed that the existing ones were all unsuitable, either for
technical or licensing reasons. Doing so is also not a big effort and
does not add any new external crate dependency to crosvm.

TEST=ARCVM Android youtube plays videos correctly when the ffmpeg
backend is used.

This replaces the bindgen-based bindings with Rust libc crate types and
constants where possible, so our custom bindings are significantly
