Fix vs_toolchain.py, possibly.

Sync a few changes with the upstream one, notably get_toolchain_if_necessary.py
needs GYP_MSVS_VERSION set. Also pull the variables that change up to the top.
This diverges a bit more from the upstream one, but we're already heavily
diverged. If we ever need to support two concurrent toolchains, I'll bring us
closer to parity.
