Transition relevant components that use open prop to expanded per design decision

[Elijbet]

Description

block and list-item use open prop, but should use expanded per design decision. They need to transition to using expanded instead.

list-item has both open and closed. It looks like it should be expanded and closed.

  /** When `true`, the item is open to show child components. */
  @property({ reflect: true }) open = false;
  
  /** When `true`, hides the component. */
  @property({ reflect: true }) closed = false;

Proposed Advantages

Alignment with the design decision and consistency across components.

Which Component

block
list-item
and other relevant components
