[menu-bar] Upgrade to expo SDK 56

[gabrieldonadel]

Why

We should upgrade to Expo SDK 56 in order to try out the outOfTreePlatforms experiment flag.

How

• Bump expo dependencies to SDK 56 (canary because of outOfTreePlatforms experiment) and run npx expo install --fix.
• Remove the two existing expo patches
• Adopt outOfTreePlatforms experiment
  • Removes the resolveRequest hook in metro.config.js that rewrote react-native to react-native-macos for the macos platform.
  • Removes the getModulesRunBeforeMainModule override that injected both InitializeCore files.
  • Simplifies the Podfile to use the standard reactNativePath instead of the -macos suffixed path, and switches react-native-config to the macos platform with --source-dir set explicitly.
  • Adds patches/react-native-macos+0.81.6.patch to (a) make react-native.config.js tolerate @react-native-community/cli not being installed and (b) let the Cocoapods autolinking script fall back to ios project/platform config when macos keys are absent.
• Replaced @react-native-clipboard/clipboard with expo-clipboard
• Replaced SystemIconView local module with expo-symbols

Test Plan

• Run menu-bar app locally

Can't we use 56.0.12? Didn't we backport it?
