[FEATURE REQUEST] Sort Gcode files by "date modified" or leave them unsorted as provided by host/TFT

[rondlh]

Is your feature request related to a problem? Please describe. Typically I want to print the last file I copied to the USB flash drive in my TFT display when I issue a M20 U: (list USB files). Unfortunate ESP3D sorts the files alphabetically, so I have to dig around to find the file I want to print.

Describe the solution you'd like Add an option to 1. sort the files alphabetically, or 2. don't sort them because the TFT handles this already.

Describe alternatives you've considered This can also be hard coded, then leave it up to Marlin or in my case the TFT to provide the files in the required order (which can be configured).

Additional context I use ESP3D V3.0, which I can recommend over V2.1
