hw/i386: Remove the deprecated machines 0.12 up to 0.15
These machines can't be used reliably for migration anymore, quoting https://lists.gnu.org/archive/html/qemu-devel/2018-12/msg04516.html : " due to the introduction of the memory API, the firmware is not migrated correctly from source to destination. On QEMU <1.3 the 0xf0000-0xfffff area is basically a copy of the higher 0xffff0000-0xffffffff area, while on more recent versions it is initialized with zeroes and the firmware copies from 0xffff0000 to 0xf0000. When you migrate from old to new QEMU, after reboot there's nothing at 0xf0000 and bugs ensue. " The pc-0.x machines have been marked as deprecated since QEMU v4.0, so it is time to remove them now. And while we're at it, mark the remaining pc-1.x machine types as deprecated now, too, so that we finally only have "pc-i440fx" and "pc-q35" machine types left (apart from the non-versioned "isapc" and "microvm") once we remove them in a couple of releases.

These machine types are very old and likely can not be used for live migration
from old QEMU versions anymore. A newer machine type should be used instead.
