[Mac] Initial Instant implementation.

This is a very rough cut.  Many things are still unfinished and will be fixed in future CLs:
- Clicking on instant results clears the results.
- Suggestions do not work yet.
- The omnibox popup overlaps with instant results.
- HTTP auth dialogs cause crashes.

BUG=56385
TEST=No visible impact when --enable-match-preview is not set on the command line.
TEST=Instant results should appear when typing in the omnibox.
TEST=Instant results should disappear when clicking outside the browser window or clicking on devtools or the sidebar.
