Vulkan backend doesn't work in the Emulator

[pixelflinger]

Simply running the hello-triangle sample in the emulator with the vulkan backend reproduces the problem.

• enabling vulkan: adb shell setprop debug.filament.backend 2

The application will crash with this error:

Filament              com...ndroid.filament.hellotriangle  E  PanicLog
                                                              in void utils::panic(const char *, const char *, int, const char *):34

The error is VK_ERROR_FEATURE_NOT_PRESENT

Hmm, I'm not seeing this. I used a emulated P6pro with API 33. Do you have details of your emulated device?

I'm unable to repro, please reopen if you're still seeing this.
