Add option to hermesProfilingIntegration to only profile Hermes JS

[krystofwoldrich]

Description

When profilesSampleRate set in Sentry.init of the React Native SDK both Hermes JS and Android JVM or iOS native profiler are recording.

This issue is proposing an option to only enable Hermes JS profiling if user doesn't want to profile the native threads.

Sentry.init({
  profilesSampleRate: 1.0,
  integration: [
    Sentry.hermesProfilingIntegration({
      platformProfilers: false
    }),
  ],
})
