[Benchmarking] Updated the dimension to ensure homogeneous fleets: Windows 7 Nvidia GPU Perf

In order to ensure homogeneous fleets, we need to have more specific
dimension values when looking for bots. This set of CLs updated some
existing dimensions, and added the synthetic_product_name values for
dimensions if appropriate.

This CL updated the dimensions for Win 7 Nvidia GPU Perf:
 - Added synthetic product name 'PowerEdge R220 [01] (Dell Inc.)';
 - Updated GPU from '10de:1cb3' to '10de:1cb3-23.21.13.8792'

Please check the link below for the available bots based on the
old/new dimensions:
