Reland "[fuchsia] Exclude SwiftShader and Vulkan libs from CastRunner."

This is a reland of 54ad18ef

Removes the Vulkan validation library from the exclusion list,
since it is not reliably present across all build configurations.

Original change's description:
> [fuchsia] Exclude SwiftShader and Vulkan libs from CastRunner.
>
> Removes large libraries that were pulled in as a result of an indirect
> but necessary dep on Blink.
>
> The exclusions can be removed along with the Blink MessagePort
> dependency, once a fix for crbug.com/1126571 lands and is
> integrated with NamedMessagePortConnector.
