This removes some overhead from tc_draw_vbo and increases the maximum number
of draws per batch from 153 to 192 in u_threaded_context.

We need to do MSAA clear on the 3d pipe, it seems to not work out
properly on 2d pipe (at least for 4x MSAA and heights that are not
multiple of 16).

This matches what blob and tu seem to do.  Fixes the following with

`fixup_draw_state()` was updating `ctx->dirty` after it had already been

It turns out that this clears CP_LOAD_STATE6 packets, including
disabling any pending loads for SS6_INDIRECT/SS6_BINDLESS (these loads
don't actually happen until the draw itself, and I'm not sure if they
happen if the state is unused by the shader) and marking constants and
UBO descriptors loaded with SS6_DIRECT as invalid. It's used very
differently from HLSQ_UPDATE_CNTL on a4xx from whence the name came, and
unlike on a4xx it's not readable, so this probably doesn't line up with
HLSQ_UPDATE_CNTL on a4xx.

This was already done correctly for the indirect variants, and turnip
was setting the correct value, but it seems freedreno missed the change
in the non-indirect variant. Also, fix a misspelling of "indices" and
add a type to INDX_SIZE.

In particular, properly detect reversal of depth-test direction.
With that we can remove a lot of cases where we were unnecessarily

Unlike other conditions which prevent early-discard of fragments, kill

Final cleanup commit now that they're the same.

We weren't filling in the tess mode of the key, or setting has_gs on GS
shaders, resulting in assertion failures when NIR intrinsics didn't get
lowered.

We have to make a guess at prim mode for TCS, but it should be better to
have some shader-db coverage than none, and it will avoid these failures
happening when we start precompiling shaders.

In detecting the case where we actually do need to re-emit LRZ state
(due to new batch), we were checking `ctx->last.dirty` to detect when
we cannot trust previous state.  But this is cleared before we check
it.

Move where it is cleared to the end of the draw_vbo() path.

This is one of the hotter pkt7 packets, since it is guaranteed to happen
on every draw.  Switch to OUT_PKT() for less driver overhead in the draw
path.

Slight bit of cheating for using CP_DRAW_INDX_OFFSET_0 for the first
dword in all cases.  Possibly *gen_header.py* could be more clever
and use typedef's in the cases of bitsets like vgt_draw_initiator.
But this works out because it is always the first dword.

We should only rely on overflow detection for indirect draws, where we
have no other option.

This doesn't use quite the worst-possible-case sizes, which in practice
seem to be ~20x larger than what is required.  But instead uses roughly
half of that.

Running the complete deqp_gles2 seems to trigger an overflow in lrz
cmdstream.  We skip the blit clear fast-path if there have been any
draws (so mid-batch clears of any attached buffer hit the 3d pipe).
Which means it is safe to simply discard any lrz clear rendering.

This lets us move PC_PRIMITIVE_CNTL into the rasterizr stateobj, rather
than unconditionally emitting it directly in the cmdstream on every
draw.

This also starts adding some tracking about previous draw state, so that
following patches can limit some of the register writes we currently
emit on every draw.
