[sw] Introduce mmio_region_memcpy_from/to_mmio32

This change introduces the `mmio_region_memcpy_from_mmio32` and
`mmio_region_memcpy_to_mmio32` functions by refactoring some code from
the `spi_memcpy` function in `dif_spi_device.c`. These functions can
be used copy blocks of memory between MMIO and main memory while ensuring
that MMIO accesses are both word-sized and word-aligned.
