stm32/uart: Add ability to have a static built-in UART object.
...
A static UART is useful for internal peripherals that require a UART and
need to persist outside the soft-reset loop.

stm32/uart: For UART init, pass in params directly, not via HAL struct.
...
To provide a cleaner and more abstract C-level interface to the UART.

stm32/uart: Remove HAL's UART_HandleTypeDef from UART object struct.
...
This UART_HandleTypeDef is quite large (around 70 bytes in RAM needed for
each UART object) and is not needed: instead the state of the peripheral
held in its registers provides all the required information.
