Given a master fd we can then override the priority of the context

Using these overrides was recommended by Christian instead of trying
to submit from a master fd, and I am adding a way to override a
single context instead of the entire process so we can only upgrade
a single Vulkan queue and not effectively the entire process.
Reused the flags field as it was checked to be 0 anyways, so nothing

[Why]
Hardware support for Delta Color Compression (DCC) decompression is
available in DC for GFX9 but there's no way for userspace to enable
the feature.
Enabling the feature can provide improved GFX performance and
power savings in many situations.
[How]
Extend the GFX9 tiling flags to include DCC parameters. These are
logically grouped together with tiling flags even if they are
technically distinct.
This trivially maintains backwards compatibility with existing
users of amdgpu_gem_metadata. No new IOCTls or data structures are
needed to support DCC.
This patch helps expose DCC attributes to both libdrm and amdgpu_dm.

The AMDGPU_SCHED_OP_PROCESS_PRIORITY_OVERRIDE ioctls are used to set
the priority of a different process in the current system.
When a request is dropped, the process's contexts will be
restored to the priority specified at context creation time.
A request can be dropped by setting the override priority to
AMDGPU_CTX_PRIORITY_UNSET.
An fd is used to identify the remote process. This is simpler than
passing a pid number, which is vulnerable to re-use, etc.
This functionality is limited to DRM_MASTER since abuse of this
interface can have a negative impact on the system's performance.

Add a new context creation parameter to express a global context priority.

* AMDGPU_CTX_PRIORITY_HIGH_SW
* AMDGPU_CTX_PRIORITY_NORMAL
* AMDGPU_CTX_PRIORITY_LOW_SW
* AMDGPU_CTX_PRIORITY_LOW_HW
The driver will attempt to schedule work to the hardware according to
the priorities. No latency or throughput guarantees are provided by
this patch.
This interface intends to service the EGL_IMG_context_priority

This creates a new command submission chunk for amdgpu
to add in and out sync objects around the submission.
Sync objects are managed via the drm syncobj ioctls.
The command submission interface is enhanced with two new
chunks, one for syncobj pre submission dependencies,
and one for post submission sync obj signalling,
and just takes a list of handles for each.
This is based on work originally done by David Zhou at AMD,
with input from Christian Konig on what things should look like.
In theory VkFences could be backed with sync objects and
just get passed into the cs as syncobj handles as well.
NOTE: this interface addition needs a version bump to expose
it to userspace.
