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

[antiagainst]

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: 19.616u

LGTM! Thanks!
I'm currently have access only to "mobile" gpu "GeForce GTX 1050 Mobile":
Compute shader execution time: 15.360us
Command buffer submit time: 7us
Wait idle time: 155us

Ah, nice to have another data point! :)
