  [mlir][vulkan-runner] Make vulkan runner use GPU device memory

To be able to have more meaningful performance out of workloadsi going through
the vulkan-runner we need to use buffers from GPU device memory as access to
system memory is significantly slower for GPU with dedicated memory. This adds
code to do a copy through staging buffer as GPU memory cannot always be mapped
on the host.
