perfetto-ui: Remove engine worker proxy hacks
Previously to m69 you could not create a worker from a worker. Due to
this when creating the WASM engine workers (from the controller worker)
we proxied the request to the main thread *which created a worker and a
a message channel then sent one end of the channel to the engine and one
end to the controller). Now that m69 is stable we can remove this
complexity.
