Tracking issues for updates for FRAME/Substrate for PBA5 Singapore

[kianenigma]

I am using this issue to track some changes to polkadot-sdk that would require updating content for the next PBA-round.

• Extrinsic Horizon paritytech/polkadot-sdk#2415
• Experimental RuntimeDebug -> Debug substitutions. paritytech/polkadot-sdk#3107
• Reason why pallet macros are the way they are: Fix pallet error spam when there is really just one simple error paritytech/polkadot-sdk#213

I originally misunderstood the purpose of this issue, and my comment was off-topic. I've opened a new issue 966 for the thought I wanted to share instead.
