Code Review
This pull request updates IsKnownBadDriver to blacklist older Adreno GPUs (version 630 and below) for the Vulkan backend, forcing a fallback to OpenGL ES on these devices. This is a workaround for issues like broken framebuffer fetch on these older GPUs. The unit tests have been updated accordingly to verify this new behavior.

These GPUs require additional flags in WorkaroundsVK that affect key features used by the Vulkan back end such as framebuffer fetch. The OpenGL ES back end will likely be more reliable on these devices. Fixes flutter#177380
