Update to VS 2015 package with embedded UCRT

Recent packaging changes in depot_tools have given us a package that
appears to build Chromium with VS 2015 on machines without the UCRT
installed. This switches VS 2015 builds to this package.

This needs to be done separately from the switch to VS 2015 so that if
that change is reverted we don't needlessly revert toolchains.

Still waiting on try jobs, but it looks like this is golden.

I want this separate from the switch-to-VS2015 CL, for cleaner reverting.
