mbox_msg: Move handler table to struct mbox_context

This allows us to provide alternative implementations for the handlers
as necessary. The vpnor feature, which enforces the read-only property
of FFS partitions, requires this for handling CREATE_WRITE_WINDOW.

test: mbox: LPC reserve memory size is not MTD size

The backing file for the LPC reserved memory region was being allocated
as the size of the MTD device. These sizes are completely unrelated.
The current configuration causes segfaults when the reserved memory
region exceeds the size of the flash.

Instead, resize the backing file once we know how big it needs to be.
Thankfully __init_lpc_dev() doesn't need the file to be sized to the
reported reserved memory size.

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.

The `sed` invocation catches a lot of function documentation, so the
hunks were manually added to avoid removing information that we want to
keep.

Cleans up residuals from failed tests in the source tree by moving them
