We're going to enable the DG2 modifier. Account for the reduced plane
count that exists with it.
Also add an assert to make it clearer that the aux in use is CCS.
Otherwise, it may not be obvious because of the generic compression
names being used here.

We're going to enable the DG2_RC_CCS modifier in anv. Add and use this
function to prepare for the new plane count that comes with that
modifier.
iris is left alone for now because it supports more modifiers than
isl_drm_modifier_get_score is aware of.

Before this change, anv_get_image_format_features2 reported support for
ASTC formats with any modifier (even those not supported by anv). But,
we didn't intend to support that compressed image format with modifiers.
With this change, the format feature function reports no support for
modifiers on ASTC-formatted images.
This prevents the next patch from causing assertion failures due to
unsupported modifiers.

We'd eventually like to use an ISL helper that doesn't support
DRM_FORMAT_MOD_INVALID. Prepare for this by replacing the invalid value
with the modifier associated with the BO's tiling in more cases.

Partial renders exist to the spill the tilebuffer to memory, there's nothing to
do if it's already spilled (and would just waste memory bandwidth and create a
feedback loop).

To accommodate framebuffers which exceed tilebuffer limits, we'll need to spill
render targets to main memory. In effect, we need to emulate an immediate-mode
renderer for some render targets. This decision is made on a per-render target
basis. In our tilebuffer layout calculation, rather than asserting that all
render targets fit, introduce a notion of spilling.
This doesn't actually implement spilling -- it just pushes the assert failure
down to the users. But it's progress.

This is internally used by the hardware when writing to the tilebuffer. We need
to use it externally to spill multisample render targets.

We need these fencing intrinsics because our image caches aren't coherent with
memory. Furthermore, we need some sync intrinsics for imageblocks (which are
spicy images). These are a stub of what the final fragment shader interlock
implementation will look like, or what a real Metal-grade imageblock
implementation needs, but this is good enough for handling the sync requirements
with spilled render targets.

This is equivalent to texture_load but cannot be reordered, since it might be
writeable.
It also sets bit 43. This needs more investigation, but it fixes

Bizarrely, the clamps/wrap modes are respected so we need to set them
appropriately for correct out-of-bounds behaviour (returning all zero). That in
turn means we can't use whatever sampler is already there, instead we need to
allocate a dedicated sampler just for txf. Good news is we have an extra sampler
state register available for the purpose.
