android vulkan: disallow noflags memory types again for AHB (for now)

bug: 134773396

This CL makes BasicVulkanGpuTests pass again, via disallowing NVIDIA's
sysmem memory types (as they dont work well with dedicated/external).

The better (upcoming) solution is to query in the beginning what memory
types correspond to dedicated + external on the host in the first place,
instead of guessing based on heuristics.
