@DoNotStrip ReactModalHostView to prevent instacrash on release (facebook#52195)

Summary:
Pull Request resolved: facebook#52195

RNTester is currently instacrashing on release due to use minifying the `ReactModalHostView`.
In that class there is a static method that is accessed by JNI so we should annotated this class
as `DoNotStrip` as otherwise we won't be able to access it.
