hostmem-file: Add "discard-data" option
The new option can be used to indicate that the file contents can
be destroyed and don't need to be flushed to disk when QEMU exits
or when the memory backend object is removed.
Internally, it will trigger a madvise(MADV_REMOVE) call when the
memory backend is removed.
