Fuchsia: Add BUILD.gn for ret2spec_sa demo
* ret2spec_sa is a demo of a Spectre V2 variant focused on attacking
return address stacks / link stacks.
* Add the demo as a binary to get started; next we will wire in our
mitigations and test the building blocks (for example, x86_ras_fill)
Bug: 12540 Speculative Execution Mitigations.
Bug: 33667 Spectre mitigations?
