tools,gyp: add support for MSVC cross-compilation

This change means that GYP can now generate two sets of projects: one
exclusively for a host x64 machine and one containing a mix of x64 and
Arm targets. The names of host targets are fixed up to end with
_host.exe, and any actions involving them are fixed up. This allows
compilation of Node on an x64 server for a Windows on Arm target.
