Switch Windows to VS 2019 toolchain (#339)

Mirrors the change from https://chromium.googlesource.com/chromium/src/+/8e82c6ab1bc2223fa25f1a127b65071d2d58ae36%5E%21/

Also adds a new variable needed to build ToT ANGLE. This is because the toolchain change is unfortunately linked to rolling ANGLE at the same time, since the current ANGLE pull has build errors under VS 2017, but ToT hits internal compiler errors with the old toolchain, so they need to be updated in lockstep.

Part of fix for https://github.com/flutter/flutter/issues/48831
