[Autofill] Limit GetOwned[Autofillable]FormControls() to connected elements

This CL restricts GetOwned[Autofillable]FormControls() to connected
elements. The motivation is that this allows for further
simplifications. The justification is that disconnected fields have
caused some issues in the past (see crbug.com/347059988 and
crrev.com/c/5664758) and the affected calls appear to have no
interest in disconnected fields either.

The CL also removes GetOwnedFormControls() from the public header
because all existing callers outside of form_autofill_util.cc use
GetAutofillableOwnedFormControls() and the risk of confusion seems
greater than the chance of callers really wanting non-autofillable
fields. Even the callers inside form_autofill_util.cc should maybe
call GetAutofillableOwnedFormControls() instead.

Logo Chromium

Chromium is an open-source browser project that aims to build a safer, faster, and more stable way for all users to experience the web.

The project's web site is https://www.chromium.org.

To check out the source code locally, don't use git clone! Instead, follow the instructions on how to get the code.

Documentation in the source is rooted in docs/README.md.

Learn how to Get Around the Chromium Source Code Directory Structure.

For historical reasons, there are some small top level directories. Now the guidance is that new top level directories are for product (e.g. Chrome, Android WebView, Ash). Even if these products have multiple executables, the code should be in subdirectories of the product.

If you found a bug, please file it at https://crbug.com/new.
