Add support for advanced blending (VK_EXT_blend_operation_advanced and
GL_KHR_blend_equation_advanced), enabling around 40 advanced blend modes
including multiply, screen, overlay, HSL modes (hue, saturation, color,
luminosity), Porter-Duff modes, and extended modes like lineardodge
and vividlight.
Advanced blending slots into the existing blending logic alongside logic
operations and standard blending. The implementation supports both
premultiplied and non-premultiplied alpha for source and destination, and
provides three overlap modes (uncorrelated, conjoint, disjoint).

Move the blend equation helper functions (blend_multiply, blend_screen,
blend_overlay, etc.) from gl_nir_lower_blend_equation_advanced.c to a
new shared header file nir_blend_equation_advanced_helper.h.
These helpers implement the mathematical blend operations defined by
KHR_blend_equation_advanced and will be reused by the new NIR lowering
pass for VK_EXT_blend_operation_advanced.

Implement state management for VK_EXT_blend_operation_advanced. Add
MESA_VK_DYNAMIC_CB_BLEND_ADVANCED dynamic state and parse
VkPipelineColorBlendAdvancedStateCreateInfoEXT during pipeline creation.
The parsed state is propagated to per-attachment fields for
src_premultiplied, dst_premultiplied, blend_overlap, and clamp_results.
Implement vk_common_CmdSetColorBlendAdvancedEXT for dynamic state
updates. When the extension info is not provided, set Vulkan spec
defaults of srcPremultiplied=true, dstPremultiplied=true, and
blendOverlap=UNCORRELATED.
Per Vulkan spec, attachmentCount is ignored when COLOR_BLEND_ENABLE,
COLOR_BLEND_EQUATION, COLOR_WRITE_MASK, and COLOR_BLEND_ADVANCED are
all dynamic. When advancedBlendCoherentOperations is not enabled, mark
COLOR_BLEND_ADVANCED as dynamic upfront in vk_get_dynamic_graphics_states()
so downstream code only needs to check the dynamic bit.

The code currently don't remove blocks, when a block is about to become
empty, the code will replace the last instruction with a NOP.
If we want to have actual block removals again, there are other
strategies than removing them as we iterate (e.g. allow empty blocks
and then collect them in a pass or right after iteration).
So remove those macros.

This optimization doesn't work when the ray query index isn't uniform across
the subgroup, which is something the spec allows. While there are some smart
ways to fix this and still avoid unnecessary spilling, its not worth investing
the time until we find a realtime raytracing workload that actually needs to
use multiple live ray queries for something.

This becomes more complex for gen8, as the lrz-status is per-slice.
Additionally the lrz-status layout isn't "stable" between GPUs of a
given generation.. the hw can change the layout, as it's not really
considered a sw interface.
Dropping HIC support for depth images removes one of two places in
the driver that reach into the lrz-status memory. The other is
tu_trace_end_render_pass(), but that is relatively safer.. at the
point that it is reading the status, all slices should be in the
same state.
Since HIC is not required for depth images, lets just delete some
code and not have this problem.

It turns out that it was intended to round down when dividing the
framebuffer size by FDM size and all other implementations of
VK_EXT_fragment_density_map did that. We followed the spec, which
doesn't say to round (which is equivalent to rounding up), but the spec
will be updated to reflect the intended behavior.

There were a few missing things here:
- The max_waves can be odd even when wavesize_granularity = 2, unlike
with registers, so we should not multiply by wavesize_granularity.
This means we have to double branchstack_size to compensate.
- The actual limit was half what it should be on a6xx-a7xx, because when
I originally calculated this computerator was using the wrong
branchstack units. We need to double branchstack_size again.
- We should limit the branchstack based on max_branchstack and align it
to 2 on a5xx+, as we do when programming the HW.
- On a8xx the limit is doubled compared to a7xx to compensate for losing
wave128.
Fix all of these.

The branchstack starts one bit lower, and we have to round to the next
even value instead of dividing by 2. This matches the actual HW
definition and will make the next commits simpler.
