Short benchmarking in CI with frame-omni-bencher + extract chain-spec-builder stuff to get_preset #379

This PR introduces a new CI pipeline for checking and running runtime benchmarks as part of the test pipelines. This means we will now know if any changes break the benchmarks.

The pipeline is based on downloading frame-omni-bencher (building it in-place is too expensive for every matrix run) and running it with a minimal setup: --steps 2 --repeat 1.

Another part of this PR splits the default genesis setups from chain-spec-generator and moves them to the sp_genesis_builder::GenesisBuilder::get_preset runtime API implementation for every runtime, which is required by frame-omni-bencher.

Closes: #197
Relates to: #298
Relates to: #324

  • Does not require a CHANGELOG entry

Future works

When this issue is fixed, I will rewrite weight-generation.md. The new version will be significantly simplified, with instructions to simply download frame-omni-bencher, build the runtime WASM, and run it—no other steps will be necessary.

2024-07-18 14:45:51 Using the chain spec instead of the runtime to generate the genesis state is deprecated. Please remove the `--chain`/`--dev`/`--local` argument, point `--runtime` to your runtime blob and set `--genesis-builder=runtime`. This warning may become a hard error any time after December 2024.

You could use: with_genesis_config_preset_name.

This would allow to fetch the preset from the wasm blob, w/o necessity to natively compile the runtime,
