[Compiler]: Consider the `dispatch` fn from useActionState and useFormState to be non-reactive

[josephsavona]

What kind of issue is this?

• React Compiler core (the JS output is incorrect, or your app works incorrectly after optimization)
• babel-plugin-react-compiler (build issue installing or using the Babel plugin)
• eslint-plugin-react-compiler (build issue installing or using the eslint plugin)
• react-compiler-healthcheck (build issue installing or using the healthcheck script)

Repro steps

Align with #29665, considering the dispatch function returned by useActionState and useFormState to be non-reactive.

This requires updating REACT_APIS in Globals.ts to define these hooks and their return type, and annotate the dispatch function as non-reactive. See the definition for useState as an example.

How often does this bug happen?

Every time

What version of React are you using?

For anyone interested in contributing: This requires updating Globals.ts and ObjectShape.ts:

• Define new types for the return value of these hooks, similar to how the type of BuiltInUseStateId is defined in ObjectShape.ts
• Define the hooks themselves (using those new types as the return types) in Globals.ts, similar to how useState is defined in the REACT_APIs variable.
• Add fixtures that demonstrate usage of these apis, similar to the playground above.

dispatch from useReducer is also considered reactive at the moment as far as I can tell: https://playground.react.dev/#N4Igzg9grgTgxgUxALhAMygOzgFwJYSYAEAwhALYAOhCmOAFAJRHAA6xRchYORA2jwCGOBABoiAEzxhKwuAAsAukQC8RKGAQAlBBKiIYTANzt2RTt16EAylABG5PLzVNVAPhZnzk6bJwLjLwBfU0wvGAQcWGIAHgAxCAgiG3tHHBVgFIcnIKIAejcTTCCQIKA

Hi everyone! I'd love to give this one a try if it's not assigned already

[josephsavona]

@hieudo-dev sure, give it a try!

Hello, I am a junior developer. Is it possible for me to participate in this issue? Open source React is very important to me. It's a library that I particularly love since I discovered it. I wish to improve my skills and learn more about it.
Thank you for taking the time to respond to me.
