Improve shortcuts experience in android

[SheikhAzharuddi]

Please allow ability to view more than 8 shortcuts per view , option to view only pinned sites rather than generated ones..both features are present in Firefox fork - iceraven so why cant mozilla fix it for all? Besides these were present long back in 2021 but mozilla UI team decided to remove this , not sure why.

Please fix this..it does not make sense to limit the ability to view 8 shortcuts when entire screen is available (if bookmarks, recently visited etc) are disabled .

Let user decide but please don't restrict🙏🏻
