* Upgrade to Mozilla Android components 15.0.0-SNAPSHOT
* Update findinpage integration to use browser-state
* Use new UseCases APIs after download migration.
There is a "unused" lint suppression in place with the comment
"Referenced from XML". I found no such usage.
It's documentation says that this Behavior will always position FindInPageBar
above BrowserToolbar but the current code ensures
BrowserToolbar.visibility == GONE when FindInPageBar.visibility == VISIBLE
so there's no need for such behavior.
Previously we needed to set a static launch function to be invoked when the find in page
integration should be launched. Now we can access the integration class directly and
can avoid the static property that caused issues when used by multiple activities.
