[omnibox][memories] Nav intent filtering for cluster suggestions.

Currently, cluster actions are hidden when we detect nav intent.
Specifically, when both a) the top scoring suggestion is a navigation
(as opposed to search) and b) it's scored at least 1300.

This CL adds the same restriction to cluster suggestions.

This reuses the existing param 'omnibox_action_on_navigation_intents' &
'omnibox_action_on_navigation_intent_score_threshold' params shared by
the action filtering.

Unlike the action filtering which looks at all result suggestions after
deduping, culling, etc; cluster filtering looks at only search and
history URL providers' suggestions before dedpuing, culling, etc. So
they may differ, but since we're mostly concerned with high scoring
suggestions, and history URL is the dominant nav provider, this should
be sufficient.

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.
