Console example doesn't duplicate code in `console` component. Linenoise has been improved: it now has a parametrized command line length. It is now possible to paste data efficiently to the console. Note: this can only be done if the cursor is at the end of the line. Closes https://github.com/espressif/esp-idf/issues/7057
