Add back transitive freeze functions option

Adds back a mode to transitively freeze function expressions, independently from 
the mode to preserve existing manual memoization. This lets us experiment with a 
few variants: 

* Preserve existing memoization 

* Validate existing memoization with: 

* `enableAssumeHooksFollowRulesOfReact` && 
`enableTransitivelyFreezeFunctionExpressions` 

* `enableAssumeHooksFollowRulesOfReact` only 

* neither of those flags 

Note that `enableTransitivelyFreezeFunctionExpressions` alone probably doesn't 
make sense, it's more aggressive than 

`enableAssumeHooksFollowRulesOfReact` so we might as well try them together.
