generate bridgesupport of static frameworks

* Test case
```
  app.pods do
    use_frameworks!
    pod 'Google-Mobile-Ads-SDK' # pre-built static framework
    pod 'google-cast-sdk' # pre-built dynamic framework
  end
```

This patch will generate bridgesupport of 'Google-Mobile-Ads-SDK'
to be able to call its API in RubyMotion app.
