Updates InferTypes to perform type inference across function boundaries. Specifically InferTypes is now responsible for driving type inference of function expressions (rather than deferring to AnalyzeFunctions to infer functions), and type inference now traverses into function expressions and infers types of free variables taking into account information from the outer context. This relies on the fact that identifier ids are consistent across function expression boundaries and that all free variables in functions are guaranteed to be effectively `const`, since we promote non-const variables used in function expressions to context variables.

An overview of the implementation can be found in the Architecture Overview.
This transform
- needs plugin-syntax-jsx as a dependency to inherit the syntax from.
- should be run before plugin-transform-react-jsx
- assume the enforcement of rules of hooks, i.e.
- only call hooks from React functions
- only call hooks at the top level
