[omnibox] [max-suggest] Add dynamic suggestions limit per # of URLs.
Adds a OmniboxDynamicMaxAutocomplete feature with 2 params,
OmniboxDynamicMaxAutocompleteUrlCutoff &
OmniboxDynamicMaxAutocompleteIncreasedLimit.
- When disabled, the omnibox allows UIMaxAutocompleteMatches
suggestions.
- When dynamic max autocompletion is enabled, the omnibox allows
suggestions up to the increased limit if doing so has URL cutoff or less
URL suggestions. It could also allow a partial increase if doing so
avoids showing more than the cutoff.
E.g. a UIMaxAutocompleteMatches of 8, URL cutoff of 2, and increased
limit of 10 translates to "show 10 or 9 suggestions if doing so includes
at most 2 URLs; otherwise show 8 suggestions.
