Remove Win10 IntelHD405 bots.
We are still testing IntelHD405 on Ubuntu16.
There are no interesting differences in gms between Braswell
(IntelHD405) and Broadwell (IntelIris6100).
Perf results are obviously worse for the slower chip, but the results
seem to track fairly well between these two bot flavors.
