Anjay-freertos-client 23.09

Features
- (commercial feature) Added support Anjay Core Persistence
- (commercial feature) Added support for SIM Bootstrap for STM32L496G-DISCOVERY with BG96 project
- Added persistence support of Security object, Server object and Attribute
  Storage, controllable through shell
- B-U585I-IOT02A and B-L462E-CELL1 targets now use external flash as storage for
  runtime configuration instead of EEPROM
- MONARCH project removed due to suspended X-Cube-Cellular support
- Added TCP support, both for management connection and CoAP+TCP FOTA downloads
- Added the Current Time resource in the Device object, and implemented real time synchronization using the cellular modem features

Improvements
- Updated X-Cube-Cellular to version 7.1.0
- Updated Mbed TLS to version 3.4.1 and enabled DTLS Connection ID support
- Enabled LwM2M 1.1 by default
- Introduced various flash footprint optimizations
- Added support for the User Button on B-U585I-IOT02A

Bugfixes
- Fixed B-U585I-IOT02A + BG96 demo app freezing in Release mode
