Effect.Capture is very similar to Effect.Read, but the only difference is that this reference is stored somewhere via a Effect.Store. Previously, any operand associated with a Effect.Store in the same instruction would get aliased -- so there was no need to explicitly differentiate between a "normal read" and "read that gets stored". This difference is now explicit with FunctionExpression where every dependency is "read" but only a few are "captured" for store (and mutation). In a follow up PR, the mutating deps will have an Effect.Capture to differentiate from the other non mutating deps (Effect.Read).

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
