commit 4b77a92aea7e6ccf635a787a18005d70e50e2dd5
Author: rouslan <rouslan@chromium.org>

Cache web contents in credit card scanner.

It's much safer to cache the WebContents instead of WindowAndroid to
deal with tab reparenting, for example. This patch changes the credit
card OCR scanner extension point to cache the WebContents instead of
WindowAndroid.

This patch also adds chrome://flags/#autofill-scan-theme-dialog to be
used by Chrome's implementation of the credit card scanner. This flag is
disabled by default and will be removed once the best theme for the scan
dialog is determined.
