Adds two separate jobs on Windows, 32-bit and 64-bit. We target a VS2017 Win10-1607 image to match what we had on Appveyor.
Modifies the runsuite_wrapper.pl script to not fork, since there is no Cygwin perl available by default. Instead, we tee to a file.
This is based on the similar work in progress for Dr. Memory: https://github.com/DynamoRIO/drmemory/pull/2326
