Description:
Adds support for presenting a survey in the Passwords screen, controlled via privacy config remote feature flag

Steps to test this PR:
Note: Since this change impacts the Sync Promo, there are a few regression test steps included. Also the survey should always take precedence over the Sync Promo.

1. Update the privacy config to use https://jsonblob.com/api/1191704313704865792
2. Reset the Sync Promos via the Debug screen (last entry), ensure Sync is disabled and that you have at least 1 password saved
3. Go to the Passwords screen and confirm the survey is present (it displays regardless of the number of passwords saved so should also show when there are none saved)
4. Enter Edit mode and confirm the survey is hidden, but re-appears when leaving edit mode
5. Perform a search and confirm the survey is hidden, but re-appears when finished searching
6. Tap the “Take Survey” button and confirm the survey loads in a new tab, and that the URL includes the parameter saved_passwords= with a value that corresponds to number of passwords saved as per AutofillSurveyManager.bucketNameFrom(count:)
7. Go back to the Passwords screen and confirm you now see the Sync Promo
8. From the Debug > Autofill Settings screen tap “Reset Autofill Surveys” to reset the survey prompt
9. Go back to the Passwords screen and confirm the survey is visible again
10. Tap the x button on the survey to dismiss it. Confirm the Sync Promo does not immediately appear
11. Back out of the Passwords screen and come back in, and confirm you now see the Sync Promo
12. Tap the “No Thanks” button and confirm there are now no header prompts
13. Back out of the Passwords screen and come back in, and confirm there are still no header prompts
