Right now we assume the fragment job chain contains only one job, but
with multilayer/multiview rendering, we want to submit fragment jobs
for all layers at once.
Turn pan_emit_fragment_job() into pan_emit_fragment_job_payload() and

The SamplerDescriptor structure has a field which describes how
floating point coordinates should be converted to fixed point.
Setting this to "true" (which causes round to nearest even) fixes
a failing CTS test.
The CTS test in question is:
dEQP-GLES31.functional.texture.border_clamp.range_clamp.linear_float_color
The OpenGL spec is somewhat vague about how rounding is to be
performed, so it appears both settings should be legal; this may
indicate a problem with the CTS. Nevertheless "round to nearest even"
is probably a better default and since it fixes the failing test we
may as well use it.

The hardware doesn't prevent us from mapping random 2DArray layers
as cube/cube arrays. The only restriction we have is on the number
of layers we pass (must be a multiple of 6 for cube arrays).
This patch makes the surface emission logic cube-agnostic, and
moves the cube face -> surface index conversion logic one layer
up to simplify things.

Panthor is a new kernel driver handling CSF-based GPUs. It's designed
around the new VM model where:
- VM management is all explicit (you get to choose where objects are
mapped in the GPU VA space)
- synchronization is explicit too (there's not BO_WAIT, and we don't
pass BOs around to serve as implicit deps)
We add a few panthor specific helpers (those exposed in panthor_kmod.h)
too:
- panthor_kmod_xxx_sync_point() are needed to make pan_kmod_bo_wait()
work with the new synchronization/VM model
- panthor_kmod_get_flush_id() is exposing the LATEST_FLUSH_ID register
- panthor_kmod_vm_handle() is providing a way to query the VM handle
attached to the pan_kmod_vm object (needed for a few panthor ioctls)
