dmaengine: stm32-dma3: add DMA_MEMCPY capability
Add DMA_MEMCPY capability and relative device_prep_dma_memcpy ops with
stm32_dma3_prep_dma_memcpy(). It reuses stm32_dma3_chan_prep_hw() and
stm32_dma3_prep_hwdesc() helpers.
As this driver relies on both device_config and of_xlate ops to
pre-configure the channel for transfer, add a new helper
(stm32_dma3_init_chan_config_for_memcpy) in case the channel is used
without being pre-configured (with DT and/or dmaengine_slave_config()).
