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.

Installed at /usr/lib/chromium/extensions/force-h264-youtube
and --load-extension flag is needed to enable the extension.

Signed-off-by: Thorsten Lannynd <t-lannynd@ti.com>
---
v2:
- Remove the flag that enables extension by default as not all SoCs support
  Wave5 and Chromium
