Switch types to use RuntimeDebug instead of gated Debug

[bkchr]

This is useful for when you want to debug in wasm and enable the
force-debug feature of sp-debug-derive.

Fixes: #4651

This should have a small, but non-zero impact on the code size if I am not mistaking. The RuntimeDebug will generate a impl block for this type in wasm that's not really printing anything, whereas the std-gated Debug is literally non-existent in wasm. Can you confirm which one is the case here? Maybe the RuntimeDebug's implementation is also stripped away by the compiler?

Either way, PR is fine to me.

This is correct. RuntimeDebug will print <wasm:stripped>

Can we please land this quickly, as I need it for debugging my code? Merci.

I merged this branch into mine. It builds now but I still get a <wasm:stripped> from my log::warn!.
I'm running a benchmark with --execution=native, so it should not be stripped, right?

I want to debug a frame_system::pallet::Config::Event, which is still Debug, RuntimeDebug needs to be introduced to substrate as well?

Benchmarks are only running in wasm.

If it is just Debug, there is no problem.

So how can I debug my event then without being stripped away?

This is using this code: https://github.com/paritytech/substrate/blob/master/frame/support/procedural/src/lib.rs#L448-L476
