<!--
If at any point it isn't actively being worked on/ready for
review/otherwise moving forward strongly consider closing it (or not
opening it in the first place). If you decide not to close it, use Draft

This adds PPro unified feedback form to iOS

**Steps to test this PR**:
1. Check Settings > Share Feedback, the existing flow should work
2. Make sure you have a PPro subscription
3. Go to Settings > Subscription Settings, the last menu item should be
FAQs and Support
4. Go to Settings > VPN > Share VPN Feedback, the existing flow should
work
5. Log in as internal user, use this for the privacy config:
http://www.jsonblob.com/api/1274015132613992448
6. Settings > Send Feedback should now let you choose between the
current browser feedback and PPro feedback form. Play with the form and
see if it works
7. Settings > Subscription Settings, the last menu item should now be
Send Feedback, again check if the flow works
8. Settings > VPN > Send feedback, this should use the new unified flow.

Smoke test these pixels as you go through the flow:

Before submitting a PR, please ensure you have tested the combinations
you expect the reviewer to test, then delete configurations you *know*
do not need explicit testing.

Using a simulator where a physical device is unavailable is acceptable.
