servo: Merge #11756 - MSVC support for Servo, and CMake builds for native code (from vvuk:servo-msvc); r=larsbergstrom

This is the base PR for MSVC builds of servo and dependent crates.  It's got replacements in the Cargo.toml to pull in the right versions, to make sure that crates were properly converted to CMake for all other platforms, not just Windows.  (Servo builds with MSVC 2015 with this PR; also with 2013, though a manual change in rust-mozjs to select a different set of bindings is needed.)

This PR isn't quite ready yet, but I want bors-servo to do builds.
