Add Goals visualisation for Pages reports in behaviour category

[tsteur]

The pages reports should have a "Display a table with goals metrics" visualisation.

We would then expect to see for each page how often it contributed to a goal conversion similar to this report: https://demo.matomo.cloud/index.php?module=CoreHome&action=index&idSite=1&period=day&date=yesterday#?idSite=1&period=day&date=yesterday&segment=&category=Referrers_Referrers&subcategory=Referrers_SubmenuWebsitesOnly

It should also show the revenue that each page contributed just like in other "Display a table with goals metrics" visualisations.

Ideally it also works for flattened reports etc.

Pages includes page urls and page titles. If it comes out of the box also entry and exit page urls/titles.
