Allow switch between legacy table of a placeholder and data grid

[ananzh]

Description

Add a html placeholder for default table.
Allow two switch types: 1) use advanced setting to disable legacy table 2) use toggle on discover page

After #5715 is done, we could replace the placeholder and merge it in.

Thanks for sharing the video in the PR @ananzh. I like that we have the setting accessible through advanced settings as well as in the application.

I do have a concern with the one in the application however - it's detached from the component that is changing (which is okay) if we provide a description on what the change could entail. Additionally, we are missing the chance to collect feedback on the new table. Here is my suggested UX for enabling new features we would like users to try.
