As we make progress towards more complex submissions we will need to split
our command buffers into smaller executable units (jobs) that we can
submit indepdently to the kernel. This will be required to implement
pipeline barriers, split subpasses that have depedencies on previous
subpasses, split render passes that use more than 4 render targets, etc.
For now we keep things simple and we only keep one job as current
recording target in the command buffer, and we generate a new one
with every subpass or with any commands we see outside of a render pass
(only vkCopyImageToBuffer for now). In the future we probably want to
optimize this by merging subpasses into the same job when possible,
etc.

Add support for V3D_DEBUG=clif. Useful to compare clif_dumps from
vulkan small-programs and the equivalent opengl ones.
As we are here we expand clif_dump_packet wrapper to use
v3d42_clif_dump_packet if needed, as the vulkan driver would use that
packet version.

Values still doesn't take into account having vertex elements data,
but keeps some of that half-done code in comments. It would be better
to do that when we get an example using it.
