stm32/uart: Always enable global UART IRQ handler on init.
...
Otherwise IRQs may not be enabled for the user UART.irq() handler. In
particular this fixes the user IRQ_RXIDLE interrupt so that it triggers
even when there is no RX buffer.

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.

stm32/mphalport: Improve efficiency of mp_hal_stdout_tx_strn_cooked.

Also simplifies the code by removing the specialised (and inefficient)
cooked functions from UART and USB_VCP.

ports: Make new ports/ sub-directory and move all ports there.
...
This is to keep the top-level directory clean, to make it clear what is
core and what is a port, and to allow the repository to grow with new ports
in a sustainable way.
