Reland "fuchsia: Set up for 3-sided roll to convert Magenta->Zircon"

Browse Source 
This is a reland of aabb893a32
Original change's description:
> fuchsia: Set up for 3-sided roll to convert Magenta->Zircon
> 
> Fuchsia changed their kernel name from Magenta to Zircon and all the
> functions and defines along with it. In order to be able to roll the SDK
> in Chromium, we first need to land with this define added in v8, so that
> can roll in to Chromium, then roll the Fuchsia SDK with this magic
> define set (CHROMIUM_ROLLING_MAGENTA_TO_ZIRCON), then actually update v8
> to reference zx_ instead of mx_ and roll that again.
> 
> Chromium-side for reference: https://chromium-review.googlesource.com/c/chromium/src/+/669139
