test: mbox: Add mbox_rspcpy()
mbox_rspcpy() copies the mboxd response into a struct mbox_msg for use
by the caller. This is useful in test cases that want to read contiguous
chunks of the flash. mbox_rspcpy() allows them to extract the current
window's offset and length to dynamically construct the
CREATE_READ_WINDOW request for the subsequent blocks.
