hw/nvme: force nvme-ns param 'shared' to false if no nvme-subsys node

Since commit 916b0f0b5264 ("hw/nvme: change nvme-ns 'shared' default")
the default value of nvme-ns param 'shared' is set to true, regardless
if there is a nvme-subsys node or not.

On a system without a nvme-subsys node, a namespace will never be able
to be attached to more than one controller, so for this configuration,
it is counterintuitive for this parameter to be set by default.

Force the nvme-ns param 'shared' to false for configurations where
there is no nvme-subsys node, as the namespace will never be able to
attach to more than one controller anyway.

hw/nvme: Add support for Secondary Controller List

Introduce handling for Secondary Controller List (Identify command with
CNS value of 15h).

Secondary controller ids are unique in the subsystem, hence they are
reserved by it upon initialization of the primary controller to the
number of sriov_max_vfs.

ID reservation requires the addition of an intermediate controller slot
state, so the reserved controller has the address 0xFFFF.
A secondary controller is in the reserved state when it has no virtual
function assigned, but its primary controller is realized.
Secondary controller reservations are released to NULL when its primary
controller is unregistered.

hw/nvme: do not auto-generate uuid

Do not default to generate an UUID for namespaces if it is not
explicitly specified.

This is a technically a breaking change in behavior. However, since the
UUID changes on every VM launch, it is not spec compliant and is of
little use since the UUID cannot be used reliably anyway and the
behavior prior to this patch must be considered buggy.

hw/nvme: do not auto-generate eui64

We cannot provide auto-generated unique or persistent namespace
identifiers (EUI64, NGUID, UUID) easily. Since 6.1, namespaces have been
assigned a generated EUI64 of the form "52:54:00:<namespace counter>".
This is will be unique within a QEMU instance, but not globally.

Revert that this is assigned automatically and immediately deprecate the
compatibility parameter. Users can opt-in to this with the
`eui64-default=on` device parameter or set it explicitly with
`eui64=UINT64`.
