Subject: [PATCH] Fix --enable-webgl-software-rendering with drivers that don't
support OpenGL
--enable-webgl-software-rendering is supposed to be used together
with mesa llvmpipe / opengl32sw.dll. However, Chromium did still use
the built-in GPU blacklist to disable features based on the hardware
GPU driver.
Avoid this by always passing --ignore-gpu-blacklist for this mode.
Task-number: QTBUG-69236
