Subject: [PATCH] Do not force gl-egl ANGLE backend on Linux

Let Chromium decide which ANGLE backend to use by keeping "default"
setting. The "gl" backend is available since
75b0d12f6 Add "default" and "gl" ANGLE implementation support to Ozone

Reportedly, the "gl-egl" backend doesn't work properly with certain GPU
drivers under X11.

Task-number: QTBUG-135786
Pick-to: 6.8 6.9
