Update EuiTablePagination to use defaults context

- default props must be manually declared using jsdocs now, since react docgen can no longer use `=` fallbacks to figure them out

- note: setting `EuiTablePagination.defaultProps` unfortunately does not work, React will automatically populate them and they don't come in as undefined
