[meta-arago,master/wrynose] meta-arago-distro: chromium: add force-h264-youtube extension

Install a lightweight Chrome extension that forces YouTube to serve
H.264 (avc1) by blocking VP8, VP9, and AV1 via MediaSource.isTypeSupported.
This enables Wave5 hardware video decoding on YouTube, which only supports
H.264 and HEVC, without requiring a third-party extension to be manually
installed through the Chrome Web Store before use.

Installed at /usr/lib/chromium/extensions/force-h264-youtube
and --load-extension is appended to the chromium-wrapper launch script.

Is Wave5 hardware video decoding supported on all SoCs? 
If not, please limit the patches to SoCs/machines that support it.

Thank you for the review. I will make the extension not enabled by default.
The only platform that does not support Wave5 but supports Chromium is
AM62x.

This will make Chromium package machine-specific. So, the same binary and 
shared state can't be re-used across different platforms of the same 
architecture, e.g. aarch64. You'd end up re-building Chromium for each 
platform individually. Chromium is already a beast and is taking forever to 
build.

Can the extension be made as a separate machine-specific package and marked 
as not compatible with AM62x. I wonder if Chromium will run just fine when 
started with --load-extension passed to not existing extenstion. Otherwise 
some run-time check for it's presence can be made in the wrapper script...
