[EuiInMemoryTable] Replace basic usages of deprecated ref method with…

… controlled `selection.selected` API (elastic#175722) ## Summary See elastic/eui#7321 EUI will shortly be removing this deprecated ref `setSelection` method in favor of the new controlled `selection.selected` prop. This PR converts basic usages of controlled selection, which should not suffer any UI/UX regressions. **Please help us QA your affected tables to confirm that your table selection still works as before!**
