Improve Autofill UI and enable inline presentations (#1181)

* Improve Autofill UI and enable inline presentations

Improves the Autofill UI in the following ways:

* Add support for Android 11 inline presentations of Autofill datasets.
* Instead of showing the identifier (app name or web origin) of the
current app on top of every Autofill dataset, it is now shown 1) as a
header dataset on Android 9 and 10 as well as 2) at the top of the
search activity on all supported versions of Android. Rationale: The
identifier is only used in trust decisions when choosing an existing
entry to fill and should feature prominently in that view, not
elsewhere.
* Show the actual identifier part of a matched entry's path, which may
differ from the identifier of the matched app/website.
* Slightly tweak the labels of Search/Generate Autofill actions to
indicate that a) this is about entries and b) the user may skip the
generation of a password and supply a custom one as well.

* Suppress lint error

* Address review comments

* Add a fixme about properly handling fill-in datasets

* CHANGELOG: add entry for inline presentation
