Revise performance measurement naming and structure (#2265)

Browse Source 
* Revise performance measurement naming and structure

- Revises naming from LayoutSpecGeneration to LayoutSpecComputation
- Adds a struct instead of an NSDictionary to retrieve performance metrics
- Includes ASEnvironmentStatePropagateDown in LayoutSpecComputation measurements

* Revise SumScopeTimer to include enable flag

* Make struct a typedef
