applications: nrf_desktop: Use Picolibc for nRF Desktop application

MarekPieta · kapi-no · commit 16f066f9cdba · 2025-03-07T16:40:42.000+01:00
Using the minimal libc implementation no longer decreases application's
memory footprint for most of the configurations. The Picolibc is used by
default in Zephyr.
