physmem: Introduce ram_block_discard_guest_memfd_range()

When memory page is converted from private to shared, the original
private memory is back'ed by guest_memfd. Introduce
ram_block_discard_guest_memfd_range() for discarding memory in
guest_memfd.

Based on a patch by Isaku Yamahata <isaku.yamahata@intel.com>.
