Lowering/layout is pretty much the same as direct descriptors. The
caveats is that since the descriptor buffers are not visible from the
binding tables we can't promote anything to the binding table (except
push descriptors).
The reason for this is that there is nothing that prevents an
application to use both types of descriptors and because descriptor
buffers have visible address + capture replay, we can't merge the 2
types in the same virtual address space location (limited to 4Gb max,
limited 2Gb with binding tables).
If we had the guarantee that both are not going to be used at the same
time, we could consider a 2Gb VA for descriptor buffers.

Those samplers live in the dynamic state base address and their offset
can be directly baking into the shaders.

We can address samplers from 3 different locations :
- binding table
- dynamic state base address
- bindless sampler base address (only Gfx11+)
Here we allow samplers to be address from the dynamic state base
address with the embedded sampler flag.

The way we implement embedded samplers will be to have the sampler
handle as a relocated constant in the shader.
This implies that 2 identical shaders with different embedded sampler
parameters must have different hash as we cannot reuse the final
shader binary.
So add the sampler hash to the descriptor set layout hash when the set
has embedded samplers.
This has the effect of creating multiple shader entries in the cache
unfortunately. An improvement over this would be to have a anv_device
map of (embedded samplers hash + shader hash) to shader in instruction
heap, so that pipeline caches only have a single entry regardless of
embedded sampler parameters.

We're about to use 2 different location for the dynamic state heap.
Which means at least on i915 we need 2 copies of all the fixed
(CPS_STATE, border colors, slice hash) stuff on the dynamic state
heap.
Let's avoid having the aux-tt tables in there too.

A number of allocations during command buffer building are sourced
from the dynamic state heap. They're not actually access using an
offset in the dynamic state heap, it just happens to be a conveninent
place.
Use different helpers for thoses so we dynamically change the dynamic
state heap location in the next commits.
