[Tile] Optimise Tile's Figma component

[alina-jacob]

Acceptance criteria

• The tile component needs more flexibility to accommodate elements above and below the Title and Description.
• We already have the slot component that allows to add extra elements, however the current implementation isn't flexible enough. This results in breaking change which isn't ideal.

Current behaviour
The current Tile component in Figma has a boolean property for "Title" and "Description". Upon toggling these off, the text goes way, but the spacing stays.

Expected behaviour
Upon toggling the "Title" and "Description" off, the text and space should go away.

Justification
This fix also makes it easier for users to customise the Tile component in a better way. It was also mentioned by a user from IBM cloud in this comment.

Workaround
There is no workaround. Hiding the entire label skews the single/multi-select and AI buttons (as shown in the image below)

Solution
This was the solution discussed in our recent Figma monthly call with Juan, Lauren and Thy.

• Create independent boolean property for "title wrapper" after adding 2 spacer blocks (one for checkbox, one for AI label).
• Absolute position the the checkbox frame and AI presence, revert frames.
• Create independent boolean property for "body text wrapper".
