Dataframe column visibility can now be controlled

[abey79]

What

• Closes Dataframe view: column visibility editor #7067
• Builds on Add a hook for views to add additional UI in the tab title bar #7438

Add the possibility to control the visibility of column:

• Time columns (except the one corresponding to the query) and component columns can be hidden by clicking on the on-hover button in their header.
• A new button in the view title bar with a popup to show/hide any column.

This also fixes a red warning showing up when latest-at queries return 0 rows (see #7449 for background).

Note to reviewer: the meat is in space_view_class.rs, which is ofc hidden by default by GitHub.
