Venus and later native contexts have their own fence context along with
multiple timelines within. Fences wtih VIRTIO_GPU_FLAG_INFO_RING_IDX in
the flags must be dispatched to be created on the target context. Fence
signaling also has to be handled on the specific timeline within that
target context.
Before this change, venus fencing is completely broken if the host
driver doesn't support implicit fencing with external memory objects.
Frames can go backwards along with random artifacts on screen if the
host driver doesn't attach an implicit fence to the render target. The
symptom could be hidden by certain guest wsi backend that waits on a
venus native VkFence object for the actual payload with limited present
modes or under special configs. e.g. x11 mailbox or xwayland.
After this change, everything related to venus fencing starts making
sense. Confirmed this via guest and host side perfetto tracing.

This patch adds functions to the plugins API to allow plugins to read
and write memory via hardware addresses. The functions use the current
address space of the current CPU in order to avoid exposing address
space information to users. A later patch may want to add a function to
permit a specified address space, for example to facilitate
architecture-specific plugins that want to operate on them, for example
reading ARM secure memory.

This patch adds functionality to enforce the requested QEMU_PLUGIN_CB_
flags level passed when registering a callback function using the
plugins API. Each time a callback is about to be invoked, a thread-local
variable will be updated with the level that callback requested. Then,
called API functions (in particular, the register read and write API)
will call qemu_plugin_get_cb_flags() to check the level is at least the
level they require.

This patch adds a function to the plugins API to allow plugins to write
register contents. It also moves the qemu_plugin_read_register function
so all the register-related functions are grouped together in the file.

The system tests (usually qos-test or migration-test) prove to be very
susceptible on the s390x runners. Although we have boosted memory and
virtual CPUs on the runners problems persist. For now mark test as
allow_failure so the its clear on the CI UI when checking test
results.
