If the user does not specify an nsid parameter on the nvme-ns device,
nvme_register_namespace will find the first free namespace id and assign
that.
This fix makes sure the assigned id is saved.

There are two reasons for changing this:
1. The nvme device currently uses an internal Intel device id.
2. Since commits "nvme: fix write zeroes offset and count" and "nvme:
support multiple namespaces" the controller device no longer has
the quirks that the Linux kernel think it has.
As the quirks are applied based on pci vendor and device id, change
them to get rid of the quirks.
To keep backward compatibility, add a new 'use-intel-id' parameter to
the nvme device to force use of the Intel vendor and device id. This is
off by default but add a compat property to set this for 5.1 machines
and older. If a 5.1 machine is booted (or the use-intel-id parameter is
explicitly set to true), the Linux kernel will just apply these
unnecessary quirks:
1. NVME_QUIRK_IDENTIFY_CNS which says that the device does not support
anything else than values 0x0 and 0x1 for CNS (Identify Namespace
and Identify Namespace). With multiple namespace support, this just
means that the kernel will "scan" namespaces instead of using
"Active Namespace ID list" (CNS 0x2).
2. NVME_QUIRK_DISABLE_WRITE_ZEROES. The nvme device started out with a
broken Write Zeroes implementation which has since been fixed in
commit 9d6459d21a ("nvme: fix write zeroes offset and count").

This adds support for multiple namespaces by introducing a new 'nvme-ns'
device model. The nvme device creates a bus named from the device name
('id'). The nvme-ns devices then connect to this and registers
themselves with the nvme device.
This changes how an nvme device is created. Example with two namespaces:
-drive file=nvme0n1.img,if=none,id=disk1
-drive file=nvme0n2.img,if=none,id=disk2
-device nvme,serial=deadbeef,id=nvme0
-device nvme-ns,drive=disk1,bus=nvme0,nsid=1
-device nvme-ns,drive=disk2,bus=nvme0,nsid=2
The drive property is kept on the nvme device to keep the change
backward compatible, but the property is now optional. Specifying a
drive for the nvme device will always create the namespace with nsid 1.

The rules to build Makefile.mtest are suffering from the "tunnel vision"
problem that is common with recursive makefiles. Makefile.mtest depends
on build.ninja, but Make does not know when build.ninja needs to be
rebuilt before creating Makefile.mtest.
To fix this, separate the ninja invocation into the "regenerate build
files" phase and the QEMU build phase. Sentinel files such as
meson-private/coredata.dat or build.ninja are used to figure out the
phases that haven't run yet; however, because those files' timestamps
are not guaranteed to be touched, the usual makefile stamp-file trick
is used on top.
