feat(ios): support LiveView

[jquick-axway]

JIRA:
https://jira.appcelerator.org/browse/TIMOB-28461

Summary:

• Support running LiveView with Hyperloop.
  • No longer modifies JS files containing Hyperloop requires/imports. (This was the issue.)
  • Now injects a hyperloop.bootstrap.js providing bindings between native types to JS files.
  • Implemented the same way as Android, which supports LiveView as of Titanium 9.0.0.
• Removed 3 year old native property access migration code.
• Updated module version to 7.0.2.

Note:
The following still won't work with LiveView because they require a native rebuild.

• Adding libraries.
• Adding Hyperloop.defineClass() calls. (Because it involves native code generation.)

Test:

1. Add this PR's hyperloop module to hyperloop-examples.
2. Build and run view LiveView: appc run -p ios --liveview
3. Go to every window in the example app and verify it works as expected.
4. While LiveView is running, open file: hyperloop-examples/app/controllers/ios/label.js
5. Change variable infoString from 'We ♥ iOS' to 'We ♥ LiveView' and save.
6. Verify app restarts without error.
7. Go to the app's Label window and verify the text has been updated.

Awesome, LGTM!

Finally, that really horrible import rewriting is gone :) That also makes my live easier for the new LiveView v2, neat!
