Probably going to use the !!prop-loader! method after #6000 merges

@thompsongl you don't need a separate prop file for class components with withEuiTheme. All EuiAccordion needs is this in its export:

export const EuiAccordion = withEuiTheme<EuiAccordionProps>(EuiAccordionClass);

Tested locally and both props table and playground work as expected. There's an extra ref prop at the bottom of the table but it's kind of whatever (IMO)
