Peripheral State and Errors functions

This subsection provides a set of functions allowing to return the State of USART
communication process, return Peripheral Errors occurred during communication process
HAL_USART_GetState() API can be helpful to check in run-time the state of the
USART peripheral.
HAL_USART_GetError() check in run-time errors that could be occurred during
communication.
This section contains the following APIs:
HAL_USART_GetState()
HAL_USART_GetError()
