[mlir][vulkan-runner] Add test to time a large vector add 

Summary:
The test performs add on vector<16384xf32> with
number of workgroups = (128, 1, 1)
local workgroup size = (128, 1, 1)

On a NVIDIA Quadro P1000, I see the following results:

Command buffer submit time: 13us
Compute shader execution time: 19.616us
