[stabilization/2106] enable higher compression of installer artifacts (#1575)

Increasing the cab file compression lowers the total windows installer size by another 0.4 GB in its current form at the traded cost of on a few extra minutes (~5 vs ~10 min on an i7-4790k) to generate them. Additionally, upping the max pre-compression cab file size to 350 MB (from 200 MB) lowers the total number of files by nearly half while still maintaining a reasonable per-cab files size post-compression.
