[FR]: WebXR support

[thenhnn]

Description

Currently Chromium supports WebXR only on Windows and Android.

Who's implementing?

• I'm willing to implement this feature myself

The problem

It's impossible to use WebXR apps on Linux.

Possible solutions

https://github.com/mrxz/webxr-linux/tree/main/chromium looks promising and doesn't seem to be very big, but works only with sandbox disabled. Chromium spawns separate process to load OpenXR runtime in isolated environment from the rest of the browser, so --no-sandbox flag seems to be unnecessary.
