cmd: add a fetch utility
Add a small utility for displaying some information about U-Boot and the hardware it's running on in a similar fashion to the popular neofetch tool for Linux [1]. While the output is meant to be useful, it should also be pleasing to look at and perhaps entertaining. The ufetch command aims to bring this to U-Boot, featuring a colorful ASCII art version of the U-Boot logo.
