v3d/compiler: Fix sorting the gs and fs inputs

ntq_setup_fs_inputs and ntq_setup_gs_inputs sort the inputs according to
the driver location. This input array is then used to calculate the VPM
offset for the outputs in the previous stage. However, it wasn’t taking
into account variables that are packed into a single varying slot. In
that case they would have the same driver_location and are
distinguished by location_frac.

This patch makes it additionally sort by location_frac when the driver
locations are equal. This can happen when the compiler packs varyings
that are sized less than vec4. Without this fix, when the VPM is used to
transmit data free-form between the stages (such as VS->GS) then it
would end up writing to inconsistent locations.

Fixes dEQP tests such as:
dEQP-GLES31.functional.primitive_bounding_box.lines.global_state.
vertex_geometry_fragment.default_framebuffer_bbox_equal

gitlab-ci: More stable URL for kernel and ramdisk artifacts, for LAVA

Place the kernel and ramdisk into a place in the file server so the URL
will only change when the contents also change.

Also put the Mesa build into a separate tarball so the ramdisk's
contents don't change every build.

With proper caching in place, all devices in the same farm need only to
download the mesa tarball once, saving time.

As we switch to MinIO for making kernels and rootfs available to LAVA
devices, we can stop using Docker to distribute them.

Instead, build when needed in separate jobs that push directly to MinIO,
from where LAVA devices can download them.

iris: Fix fast-clearing of depth via glClearTex(Sub)Image

It generates compilation warnings though,
