[oe] [meta-browser] Modern Chromium with GN

[Trevor Woerner]

Hi Jocobo,

Please have a look at
https://github.com/rakuco/meta-crosswalk/tree/chromium61/recipes-browser/chromium
from Raphael (CCed). It is an interesting and promising approach.

I have built against minnow (x86-64) and rpi3-32 (armv7ve)
successfully with pyro. I haven't had time to runtime test anything
yet. I'm still seeing a build issue with both MACHINEs against master.

It's been about two weeks since I've had time to tinker with it.

Best regards,
    Trevor
