Anjay-freertos-client 23.02

Features
- Reworked socket implementation to use X-Cube-Cellular offloaded sockets
  (Com sockets) instead of LwIP (NOTE: currently supporting only UDP)
- Added Firmware Update Object (/5) to STM32L496G-DISCOVERY and B-L462E-CELL1 projects

Improvements
- Revamped configuration of Anjay and its dependencies
- Updated Anjay to version 3.3.0

+ *   overhead for each allocated memory block
+ * - Additional memmove() for every realloc() that returned a block that is not
