ST morpho connector CN11 and CN12

The ST morpho connector consists of male pin header footprints CN11 and CN12 (not soldered by default). They
can be used to connect the STM32 Nucleo-144 board to an extension board or a prototype/wrapping board
placed on top of the STM32 Nucleo-144 board. All signals and power pins of the STM32 are available on the ST
morpho connector. An oscilloscope, a logic analyzer or a voltmeter can also probe this connector.
