Assess native Chonk verification time requirements #1635

To include:

• Understanding and documenting the points in the network where native Chonk verification time is a TPS bottleneck
• Making an informed assessment of a "good enough" target
• Assessing whether engineering-style tactics (e.g. optimistic batched IPA verification) are useful/sufficient (maybe in some places but not all?)
• Getting buy in from stake-holders on said targets
