threads). Let's cut out memory footprint for spilling by 75% :)

These two cases were flipped from the notes, leading to underestimates
of the padded vertex count, manifesting as visual corruption (random
geometry messed up). This issue was raised when noticing the corruption
went away when dramaticlaly oversizing max_index on an instanced indexed
draw, and then checking that padded_count >= vertex_count -- which
turned out *not* to be the case on certain inputs, a clear issue. Hence
looking into this routine...

Rather than creating partially within the Gallium create function and
monkeypatching on draw time with code split across N different files
with tight Gallium dependencies, let's streamline everything into a
series of maintainable routines in mesa/src/panfrost with no Gallium
dependencies, doing the entire texture creation in one-shot and thus
adding absolutely zero draw-time overhead (since we can allocate a BO
for the descriptor and upload ahead-of-time, so switching textures is as
cheap as switching pointers).
Was this worth it? You know, I'm not sure :|
