ac/nir: fix out-of-bound access when loading constants from global
Global load/store instructions can't know if the offset is
out-of-bound because they don't use descriptors (no range).
Fix this by clamping the offset for arrays that are indexed
with a non-constant offset that's greater or equal to the array
size.
This fixes VM faults and GPU hangs with Dead Rising 4.

iris: Default to X-tiling for scanout buffers without modifiers
Neither Mutter nor KWin's wayland compositors appear to use modifiers.
In the non-modifier case, iris was still trying to use Y-tiling for
scan-out surfaces, leading to this error:
(gnome-shell:7247): mutter-WARNING **: 09:23:47.787: meta_drm_buffer_gbm_new failed: drmModeAddFB failed: Invalid argument
We now fall back to the historical X-tiling for scanout buffers, which
ought to work everyone, at lower performance. To regain that, we need
to ensure modifiers are actually supported in environments people use.

The caller is responsible for setting up the ubo_addr_format value as
contrary to shared and global, it's not controlled by the spirv.
Right now clovers implementation of CL constant memory uses a 24/8 bit format
to encode the buffer index and offset, but that code is dead as all backends
treat constants as global memory to workaround annoying issues within OpenCL.
Maybe that will change, maybe not. But just in case somebody wants to look at
