Omnibox: Steady State Elisions - Implement One Click Unelide for Views

Add a flag chrome://flags/#omnibox-ui-one-click-unelide that performs
unelision whenever the omnibox is focused, via either keyboard, mouse,
or gesture tap.

This notably does not affect Query in Omnibox, as the user may still
want to refine the query.

Omnibox: Make OmniboxView::GetIcon more robust for steady state elisions

Whenever the user unelides the URL, the omnibox also enters
user_input_in_progress_ mode.

This is was harmless before, but since then we have started displaying
suggestion favicons in the omnibox, the current page's security
indicator is being clobbered by the page's favicon during unelision.

This is not correct, since unelision is supposed to be as unobtrusive
as possible.

This is going to become more noticable now that Ctrl+L triggers
unelision, as well as our future planned work for One-Click-Unelide.

This CL replaces the old logic, and keeps showing the current page's
security indicator until the user actually modifies the user text.
