In order to implement VK_KHR_external_fence, we need to back our fences
with something that's shareable. Since the kernel wait interface for
sync objects already supports waiting for multiple fences in one go, it
makes anv_WaitForFences much simpler if we only have one type of fence.

This is just a refactor, similar to what we did for semaphores, in
preparation for handling VK_KHR_external_fence.

This commit changes fences to work a bit more like BO semaphores.
Instead of the fence being a batch, it's simply a BO that gets added
to the validation list for the last execbuf call in the QueueSubmit
operation. It's a bit annoying finding the last submit in the execbuf
but this allows us to avoid the dummy execbuf.

We didn't allow them before because it didn't look like the spec allowed
it. It certainly doesn't make much sense. However, there are CTS tests
that apparently hit this. What the spec actually says is:
"Importing a payload using handle types with copy transference
creates a duplicate copy of the payload at the time of import, but
makes no further reference to it. Fence signaling, waiting, and
resetting operations performed on the target of copy imports must
not affect any other fence or payload."
A SYNC_FD has copy transference but the import may be temporary or
permanent. If you do a permanent import of something with copy
transference, I guess it's supposed to work and end up resetting the
permanent state. In any case, there seems to be no real harm in
allowing it, so why not.

Vulkan allows you to do a submit whose only job is to wait on and
trigger semaphores. The easiest way for us to support that right
now is to insert a dummy execbuf.

This patch adds an implementation based on DRM BOs. We don't actually
advertise the extension yet because we want to add a couple more paths
first.

The idea behind doing this was to make it easier to set various flags.
However, we have enough custom flag settings floating around the driver
that this is more of a nuisance than a help. This commit has the
following functional changes:
1) The workaround_bo created in anv_CreateDevice loses both flags.
This shouldn't matter because it's very small and entirely internal
to the driver.
2) The bo created in anv_CreateDmaBufImageINTEL loses the
EXEC_OBJECT_ASYNC flag. In retrospect, it never should have gotten
EXEC_OBJECT_ASYNC in the first place.

We weren't wrapping this before because anv_cmd_buffer_execbuf may throw
a more meaningful error message. However, we do change the error code
into VK_ERROR_DEVICE_LOST, so we should print a new message.
