[TASK] Fix Substrate Benchmarking framework so we can benchmark tangle

[shekohex]

Currently the benchmarking workflow is broken, not working, does not compile at all, even if after fighting with the compiler and fixing all the issues and make it compiles, it does not run and returns the following error:

./target/release/tangle benchmark pallet --chain benchmark --pallet pallet_services --extrinsic '*' --steps 50 --repeat 20 --output ./pallets/services/src/weights.rs --template ./.maintain/frame-weights-template.hbs

Output:

2024-10-02 18:10:17 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.

So it looks like it is missing some host functions for some reason: runtime requires function imports which are not present on the host: 'env:ext_ext_call_list_new_version_2', 'env:ext_ext_step_event_filter_version_1', 'env:ext_ext_gasometer_event_version_1', 'env:ext_ext_runtime_event_version_1', 'env:ext_ext_evm_event_version_1'"

And it looks like these functions comes from https://github.com/webb-tools/tangle/blob/7c12d9ef9b922cdd30118ab55c00b959dcd8d2db/primitives/ext/src/lib.rs#L36-L85

even though they are registered as you can see here: https://github.com/webb-tools/tangle/blob/7c12d9ef9b922cdd30118ab55c00b959dcd8d2db/node/src/service.rs#L79-L81

It still complains that it is missing from the runtime!

[shekohex]

It looks like we have to define the HostFunctions here too: https://github.com/webb-tools/tangle/blob/7c12d9ef9b922cdd30118ab55c00b959dcd8d2db/node/src/command.rs#L238

That actually made it works.
