Somehow we have native hardware for all of these. Suspected by staring
at the bit pattern; confirmed by poking in various texture wrap modes
into the textures mesa demo and seeing what happens.

These are conventions by the blob (a convention we happent to follow).
They are not at all intrinsic to the hardware, so now that the
convention is implemented within the Midgard stack, these defines are
wholly unused. Remove them.

It shows up as a special (magic?) attribute. We could try to be clever
and only include the extra record if gl_VertexID is actually read, but
honestly that's just extra complexity for no good reason. Might as well
just always include it; this won't be a real bottleneck, I don't think.

Just like varyings have special records for point coordinates (etc),
attributes have special records for vertex/instance ID. We can parse
these fairly easily, although they don't line up exactly with normal
attribute records.

Padded counts are numbers of the form:
n = (2k + 1) * 2^s
for k, s integers. Rather than explicitly store k and s separately and
then compute this formula on demand, it's much cleaner to store the
padded number itself, which is what you manipulate most of the time.
When you do need k,s it is easy to factor by noticing the bitwise
representation:
s = ctz(n)
k = n >> (s + 1)

We need to reshuffle to sync up the shadow coordinate temporary with the
cubemap coordinate temporary. Once that's in place, it's simple enough
(we load the shadow coordinate into .z like 2D).

My latest divination spell has uncovered a pattern in the aether.
Although the swizzle is unaligned, its format is otherwise standard.
Document this, removing the old incorrect understanding of the swizzle
(which coincided on common special swizzles only).
