Backport tracing to older wasm releases

[gnunicorn]

Once paritytech/substrate#6916 is in and paritytech/substrate#6572 adds traces to the runtime, our client provides tracing-support for wasm runtimes with the with-tracing feature is enabled. To allow for tracing all the way back to genesis, we therefor must backport these changes to each polkadot runtime at the time and build it with with-tracing enabled, and then release the wasm binaries here for download.
