GPU: Blacklist unsupported GPUs that crash during startup.

Since Blender 2.91 the TeraScale 2 based cards crash during startup.
This patch will show the user a screen that the platform they are using
isn't supported.

The GPUs have been carefully handpicked from dozens of reports. T83124,
T83127, T83103, T83091, T83045, T83065, T82750, T82889, T82925, T82640,
T82429, T82436, T82446.
