HAL CORTEX MPU Region configuration type definition

In HAL1, the MPU (Memory Protection Unit) region and attributes are configured using two structures: MPU_Region_InitTypeDef and MPU_Attributes_InitTypeDef.

In HAL2, the MPU region configuration is simplified and structured using the hal_cortex_mpu_region_config_t structure. This structure consolidates the configuration parameters for an MPU region. For the MPU_Attributes_InitTypeDef structure, it’s now set directly as an input in the config functions.
