stylo: Bug 1346052 - Add Servo_AnimationValue_Compute.
This is an interdependent patch of Bug 1346052. We need this FFI to compute the AnimationValue from a property id and a string, so nsDOMWindowUtils::ComputeAnimationDistance() can use this FFI to get the AnimationValue.

This will go back down soonish when NonZero stablizes and we can use it in
StyleArc, which I expect will be long before the memory overhead here matters.
This is a verbatim copy of the source at [1]. It won't compile on stable rust,
but I'm including it here to make the changes clear.

Replace intrinsics::abort with process::abort
This removes some unsafe/unstable code and replaces it with a new safe/stable alternative.
Note that `process::abort` is not identical to `intrinsics::abort`, since it runs global cleanups to do things like flush stderr (though neither function performs stack unwinding). I don't *think* the difference matters for our use cases.
