virtual_sdcard: Add an option to sort by date

[nhchiu]

Added an option to sort the files with modified date in reverse, so the most recently uploaded one is at the top.

It should be useful for many LCD screen users so that they can easily reprint the latest file when they are at the printer. Especially if there are a lot of g-code files or not named properly.

Self review

1. Tested on my own printer with and without the option set, and they both worked correctly. Result of running regression test cases
   • whitespace check passed
   • regression test with dictionaries 20230921 from here failed at input_shaper.test. I assume it's caused by the recent bulk sensor update and the test dictionary is out of date.

Protocol error

msgproto.error: mcu 'mcu': Command format mismatch: query_adxl345 oid=%c rest_ticks=%u vs query_adxl345 oid=%c clock=%u rest_ticks=%u

2. As stated above, I think it's beneficial to LCD screen users that don't have PC or smartphone at the place the printer is.

3. No new files created and only minor modifications to an existing class.

4. The new config option is updated in Config_Reference.md. If not specified it falls back to the default action as before so probably not needed to be documented in Config_Changes.md

@nhchiu don't bother, there are several patches made for this before, but the project manager does not want this feature.

scouring the web, you need to be part of some discord channel to get any of your commits looked after.
