Before this commit, zink_format_clamp_channel_color() ignored the format
swizzle, so it was assuming that for emulated formats like alpha,
alpha-luminance etc. that the color had already been swizzled to match
the internal format rather than the emulated one. It's somewhat confusing
that passing in e.g. A8_UNORM actually means R8_UNORM, and led to a bug
when using VK_FORMAT_A8_UNORM for texture border colors because we
didn't swizzle it back. It also wouldn't have worked for media formats
like R10X6G10X6 due to the void channel in the middle.
In order to fix this, we need to untangle the mess in its users.
For convert_color() used when clearing, this means we now need to clamp
and then swizzle instead of swizzle and then clamp, and we can drop the
hack for A8_UNORM.
For texture border colors, the state tracker duplicates colors for the
emulated formats to help drivers, which zink was previously relying on,
but fixing zink_format_clamp_channel_color() breaks this because it
assumes that those duplicated colors are useless and clamps them.
However, because we know the format we can just swizzle the border color
ourself, which convert_color() was already doing. So, we pull that out
into a common zink_convert_color() function that handles both clamping
and format emulation, and have both clearing and border color handling
use it.
This fixes A8_UNORM in turnip+zink once we enable it.

When trying to create a headless Vulkan instance without a display
device available, device enumeration would fail.
Part of the physical device creation code already accounts for a missing
display device, allow device enumeration to continue in that case too so
headless instances can be created.

I hit a problem running a set of lvp caselists with
dEQP-VK.transform_feedback.simple.draw_indirect_endqueryindexed_streamid_0_16,Crash
This was crashing due to
assert(setup->viewport_index_slot < 0);
in try_update_scene_state
This was because a previous draw had set viewport index slot to 2,
but a clear then draw sequence never resets it, so the clear gets
a scene, and when the subsequent flush happens for that scene,
the viewport_index_slot is never updated. It only gets updated on
draws.
This just resets it as lp_setup_update_state will always pick up
the correct one for the next draw.

Even though drivers are required by documentation to handle the samplers
being NULL, st/mesa changed enough so it always sets the pointer.
As being similiar to st/mesa is more important than following docs, we
simply mimic st/mesa here and meet the expectations of drivers.
In the future we want to track the set state similiar to st/mesa, so
`clear_sampler_views` will probably go away and we'll just update what
we'll need.

When a backing resource is created for a render target view when the
same resource is currently bound to a shader resource view, the content
update back to the original resource happens when the associated render
target view is unbound. But state update only happens at clear or draw
time. So if TexSubImage happens after BindFrameBuffer and before Draw,
the original texture resource that is mapped to for subimage update
would not have been updated. As a matter of fact at the subsequent state
update at the next draw, the render target views will be updated, the
content from the previous backing resource will be propogated to the
original resource, hence overwriting the changes from the last TexSubImage.
To fix the problem, this patch validates the texture resource, updates
any pending changes from the backing resource before transfer map upload
occurs.

The kernel exposes CHIP_ID, which consists of:
[63:48] const 0 / reserved
[47:32] speedbin (default 0xffff)
[31:0 ] actual gpu chip ID
Fix the 690 chip id to make it probe correctly.
Keep the existing entry for the downstream KGSL driver.
This is essentially the same as Commit 6067aba9e6 ("freedreno: Include
speedbin fallback in 740 chipid to fix probing"), except for the older
core.
