Quote: Add spacing supports

[aaronrobertshaw]

Part of: #43241

What?

Adopts padding and margin support for the Quote block.

Why?

• Offers greater design flexibility
• Improves consistency in design tooling with other blocks

How?

• Adopts padding and margin block supports

Testing Instructions

• In the site editor, add a Quote block to a page
• Style via Global Styles and confirm the editor and frontend display correctly
• Override the global styles on the block instance and confirm they display appropriately in the editor and frontend

Note: Global margins will be overridden by layout whereas block instance margins will not be. There is also an unrelated bug with the spacing visualizers that is being addressed separately.
