vhost: enable vrings in vhost_dev_start() for vhost-user devices

Commit 02b61f38d3 ("hw/virtio: incorporate backend features in features")
properly negotiates VHOST_USER_F_PROTOCOL_FEATURES with the vhost-user
backend, but we forgot to enable vrings as specified in
docs/interop/vhost-user.rst:

If ``VHOST_USER_F_PROTOCOL_FEATURES`` has not been negotiated, the
ring starts directly in the enabled state.

If ``VHOST_USER_F_PROTOCOL_FEATURES`` has been negotiated, the ring is
initialized in a disabled state and is enabled by
``VHOST_USER_SET_VRING_ENABLE`` with parameter 1.

Some vhost-user front-ends already did this by calling
vhost_ops.vhost_set_vring_enable() directly:
- backends/cryptodev-vhost.c
- hw/net/virtio-net.c
- hw/virtio/vhost-user-gpio.c

But most didn't do that, so we would leave the vrings disabled and some
backends would not work. We observed this issue with the rust version of
virtiofsd [1], which uses the event loop [2] provided by the
vhost-user-backend crate where requests are not processed if vring is
not enabled.

Let's fix this issue by enabling the vrings in vhost_dev_start() for
vhost-user front-ends that don't already do this directly. Same thing
also in vhost_dev_stop() where we disable vrings.

qmp: decode feature & status bits in virtio-status

Display feature names instead of bitmaps for host, guest, and
backend for VirtIODevices.

Display status names instead of bitmaps for VirtIODevices

qmp: decode feature & status bits in virtio-status

Display feature names instead of bitmaps for host, guest, and
backend for VirtIODevices.

Display status names instead of bitmaps for VirtIODevices.

Display feature names instead of bitmaps for backend, protocol,
acked, and features (hdev->features) for vhost devices.

Decode features according to device ID. Decode statuses
according to configuration status bitmap (config_status_map).
Decode vhost user protocol features according to vhost user
protocol bitmap (vhost_user_protocol_map).

Transport features are on the first line. Undecoded bits (if
any) are stored in a separate field.

[Jonah: Several changes made to this patch from prev. version (v14):
- Moved all device features mappings to hw/virtio/virtio.c
- Renamed device features mappings (less generic)
- Generalized @FEATURE_ENTRY macro for all device mappings
- Virtio device feature map definitions include descriptions of
feature bits
- Moved @VHOST_USER_F_PROTOCOL_FEATURES feature bit from transport
feature map to vhost-user-supported device feature mappings
(blk, fs, i2c, rng, net, gpu, input, scsi, vsock)
- New feature bit added for virtio-vsock: @VIRTIO_VSOCK_F_SEQPACKET
- New feature bit added for virtio-iommu: @VIRTIO_IOMMU_F_BYPASS_CONFIG
- New feature bit added for virtio-mem: @VIRTIO_MEM_F_UNPLUGGED_INACCESSIBLE
- New virtio transport feature bit added: @VIRTIO_F_IN_ORDER
- Added device feature map definition for virtio-rng

hw/virtio: move vhd->started check into helper and add FIXME

The `started` field is manipulated internally within the vhost code
except for one place, vhost-user-blk via f5b22d06fb (vhost: recheck
dev state in the vhost_migration_log routine). Mark that as a FIXME
because it introduces a potential race. I think the referenced fix
should be tracking its state locally.

include/hw: document vhost_dev feature life-cycle

Try and explicitly document the various state of feature bits as
related to the vhost_dev structure. Importantly the backend_features
can advertise things like VHOST_USER_F_PROTOCOL_FEATURES which is
never exposed to the driver and is only present in the vhost-user
feature negotiation.
