Subject: [PATCH] Create GHA action to run Maestro in CI (#45704)

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/45704

## Context
Running manual tests when preparing a release, it's time consuming.
We have to do the cherry picks, wait for CI to finish, and then manually test 8 configurations.

Maestro is a tool that allow us to run E2E tests automatically, and we can wire it to CI.

## Change
Create a reusable GHA to run Maestro tests on iOS

Changelog:
[Internal] - Exploration to integrate maestro
