These structures are the norm on midgard t760+, drop the bifrost names,
it's silly... unrelated to the rest of the series but while I'm messing

We discovered 2 new shader flags used when a fragment shader updates
the depth/stencil value through a ZS writeout. If those flags are not
set, the depth/stencil value stored in the depth/stencil tilebuffer
remain unchanged.
While at it, rename unknown2 into flags_hi and rename flags into
flags_lo.

As pointed out by Boris, what we were calling PAN_LINEAR depth textures
was in fact u-interleaved tiled (!), but we never noticed since we
flipped the flag used for sampling, leading to all sorts of fun bugs
when attempting to directly acess depth textures from the CPU. Which
begs the question -- if what we called LINEAR was tiled, how do we
actually render linear depth textures? It turns out the flags for AFBC
form a mali_block_format 2-bit code just like their render-target
counterparts, so we can render to any of the above.

There's only one way to encode comparison functions in the command
stream, not two. It's just that the semantics for texture comparisons
are flipped from the semantics of stencil comparison. We can factor out
that flip to common Panfrost code, rather than tying it to a second
Gallium routine.

- Also disable tiling when !hierarchy and !vertex_count
- Avoid creating polygon lists smaller than the minimum when
vertex_count > 0 but tile size smaller than 16 byte
- Take into account tile size when calculating polygon list size for
!hierarchy
- Allow 0-sized tiles in a single dimension
