asahi: ci: Rename asahi-g13g Vulkan CTS suite to asahi-agx2

Apple M1 and M2 GPUs are similar enough to use the same deqp-runner
suite. Use "agx2" as suffix to cover GPUs implementing the AGX2 ISA.
This covers at least the GPUs in all M1 and M2 SoCs.
Extend the `renderer_check` to match M2 (G14x) GPUs as well. The
original check already included M1 Pro/Max/Utra (G13S, G13C and G13D)
erroneously.
