Update SelectPanel guidelines: Add clearing guidelines for SelectPanel/SelectMenu with single/multi selections

[maximedegreve]

Currently our components are lacking guidelines as well as functionality on how clearing selections in a SelectPanel or SelectMenu should work. This is especially a problem when you have multiple items selected and quickly want to clear those

Exploration by @asiermartinez

Consider

• Selects with multi selections
• Selects with a filter input

@maximedegreve Leaving here the original Figma with all the noodles in case anyone finds it useful.

This issue seems a bit out of date - we need to add SelectPanel guidelines to the new docs altogether when we move back to the v1 component. Taking over this issue for now @maximedegreve give me a shout if you want me to open a new one
