WAM crash on Raspberry Pi 3 / master

Close for HH 8.0.3 release

The Gerrit CL is  now merged for Halibut and master.  Marking the issue as fixed.

Pull request was accepted. Gerrit CL to bump the chromium version can be found here: https://gerrit.automotivelinux.org/gerrit/c/AGL/meta-agl-devel/+/22582

Pull request reverting the offending commit "[BACKPORT] [ozone/wayland] Use gbm with in-process-gpu mode" created:

https://github.com/webosose/chromium68/pull/20

The behaviour introduced by that commits breaks web apps in the Raspberry Pi. For this to work correctly we have to backport:

• "ozone/wayland: Use modifiers provided by Wayland compositor" 

• https://chromium-review.googlesource.com/c/chromium/src/+/1795326

which it is not straightforward, because the commit is recent and depends on refactorizations and changes not present in our repository.
 
Specifically, to avoid the crash, we are interested in lines 52-65  https://chromium-review.googlesource.com/c/chromium/src/+/1795326/11/ui/ozone/platform/wayland/host/wayland_zwp_linux_dmabuf.cc#b53 
but it is recommended to backport the whole patch. For this reason and the ones commented above, we are now reverting the problematic commit with the intention of recovering those in the future once we use a more recent chromium version.

Upstream patch "[ozone/wayland] Fix crash when there is no zwp_linux_dmabuf " does not fix the issue.

The backtrace for the original crash is:
