fix: Metro inline-plugin doesn't support relative ES imports of Platform and it cause dead-code in production

[retyui]

Summary:

Metro inline-plugin doesn't work when an Platform has relative ES import

// source code
Platform.OS === 'android' 

// expected (when build for ios)
"ios" === "android" // <-- always false, so deadcode elimination algorithm can remove the code

// actual
"android" === r.default.OS

metro has own PR: react/metro#1692 (comment) but no lock it will be merged soon I think

Changelog:

[GENERAL] [FIXED] - No dead-code in production for internal usages of Platform

Test Plan:

Could we please update the inline plugin instead of reverting all these usages to require calls? I'm afraid this isn't very idiomatic, won't scale well and a lot of use cases will be reverted over time organically.

@rubennorte As I mentioned in the description an inline-plugin has own PR: react/metro#1692 (comment) but no luck it will be merged

so to devilry a simple dead-code elimination trick for all devs in the world this PR was created and hope will be available in the next release of RN

The right direction here is to fix the issue in react/metro#1692 not the import legacy requires in the react-native codebase.
