freedreno/ir3: Use immediate for flat.b's src1

According to Jonathan Marek:

  Only one immediate can be decoded in a cat2 instruction (if both srcs
  are immediates, they will use the value of the either the first or
  second one, I don't remember which) - using 2 immediates in a cat2
  instruction is only "correct" if they are both equal.

  The (i,j) in the second src of flat.b is not unused, but behaves as 0
  for any (small) integer because it is a float src. The hack I
  suggested is to set the second src equal to (immediate) first src,
  which seems to work.

This allows us to remove a couple of mov instructions or a bit of extra
constfile usage.

st/mesa: don't update vertex elements when GL doesn't change them

We rely on mesa/main to tell us whether to update vertex elements.
This decreases overhead for obvious reasons.

The select/feedback code path doesn't use this, which is why you see
unconditional "ALL" in a few codepaths.

This sequence of GL calls doesn't update vertex elements if only
the pointer and stride vary:
    glVertexPointer()
    glDrawElements()
    glVertexPointer()
    glDrawElements()
    glVertexPointer()
    glDrawElements()

gallium: add PIPE_CAP_VERTEX_ATTRIB_ELEMENT_ALIGNED_ONLY

vulkan requires that vertex attribute access be aligned to the size of
a component for the attribute, but GL has no such requirements

the existing alignment caps are unnecessarily restrictive for applying
this limitation, so this cap now pre-calculates the masks for elements
and vertex buffers in vbuf to enable rewriting misaligned buffers
