loader: reimplement loader_get_user_preferred_fd via libdrm

Currently not everyone has libudev and with follow-up patches we'll
completely remove the divergent codepaths.

Use the libdrm drm device API to construct the required ID_PATH_TAG-like
string, to preserve the current functionality for libudev users and
allow others to benefit from it as well.

v2: Drop ranty comments, pick the correct device
v3: \n -> \0 in PCI_ID_PATH_TAG_LENGTH comment (Axel).
v4: Use snprintf (Nicolai)

anv: Get rid of graphics_pipeline_create_info_extra

Now that we no longer have meta, all pipelines get created via the normal
Vulkan pipeline creation mechanics.  There is no more need for this bit of
extra magic data that we've been passing around.

anv/hiz: Perform HiZ resolves for all partial renders

If we don't, we can end up with corruption in the portion of the depth
buffer that lies outside the render area when we do a HiZ resolve at the
end.  The only reason we weren't seeing this before was that all of the
meta-based clears such as VkCmdClearDepthStencilImage were internally using
HiZ so the HiZ buffer never truly got out-of-sync.  If the CTS ever tested
a depth upload (which doesn't care about HiZ) and then a partial render we
would have seen problems.  Soon, we will be using blorp to do depth clears
and it won't bother with HiZ so we would get CTS regressions without this.

Here follows original commit message by Chad Versace:

"I'm about to implement DRI2_Fenc in intel_syncobj.c.  To prevent
