This is a re-land; the migration originally landed but broke compilation
of the 'all' meta-target, passing the CQ but breaking the waterfall.

Fuchsia's Vulkan rules have been fixed now, so things build cleanly
with this CL, and the trace-engine is now correctly specified by the
Vulkan rules themselves, rather than needing to be specified by Chromium.
