[3.2.0]

Changed

• Renamed lt_secure_memzero.h to libtropic_secure_memzero.h and moved it to include/, so it is available in HAL.

Added

• Examples: Added full certificate chain verification example for Linux SPI.
• HAL: HAL for STM32U5xx series
• Documentation: new tutorial for the TROPIC01 model - Understanding Libtropic.

Fixed

• Size of l3_chunk member of lt_l2_encrypted_cmd_req_t and lt_l2_encrypted_cmd_rsp_t structs to TR01_L2_CHUNK_MAX_DATA_SIZE.
• hal/: don't include libtropic_port.h in HAL headers if not used.
• lt_init() is successful even if TROPIC01 has invalid Application FW, so Libtropic can be used in Start-up Mode.
• STM32: securely wipe secrets when generating random numbers.
• STM32: change type of baudrate_prescaler (inside lt_dev_stm32_nucleo_f439zi_t and lt_dev_stm32_nucleo_l432kc_t) to uint32_t.
