Move subgroup_id, that's only used by CS for verx10 < 125, as part of
the payload too -- even though is not, strictly speaking.
Note the thread execution of Task/Mesh is similar enough, so we make
their common struct inherit from cs_thread_payload.

When loading a TCS or GS input, we generate some code to read the URB
handle for a particular input control point (ICP handle), which often
involves indirect addressing due to a non-constant vertex.
For example:
mov(8) vgrf148+0.0:UW, 76543210V
shl(8) vgrf149:UD, vgrf148+0.0:UW, 2u
shl(8) vgrf150:UD, vgrf145:UD, 5u
add(8) vgrf151:UD, vgrf150:UD, vgrf149:UD
mov_indirect(8) vgrf147:UD, g2:UD, vgrf151:UD, 96u
Unfortunately, the first load with 76543210V is considered a partial
write because the 8 channels of 16-bit UW data doesn't fill an entire
register, and we can't allocate VGRFs at sub-register granularity.
This causes none of the above math to be CSE'd, even though the first
two instructions are common to *all* input loads, and the rest may be
reused sometimes as well.
To work around this, we stop emitting 76543210V to a temporary, and
instead use nir_system_values[SYSTEM_VALUE_SUBGROUP_INVOCATION], which
already contains this value, and is unconditionally set up for us.
With all input loads using the same register for the sequence, our
CSE pass is able to eliminate the rest of the common math.

We found a perf regression with 9027c5df4c ("anv: remove the
LOCAL_MEM allocation bit") which seems to be that we over subscribe
local memory, leading i915 to swap things in/out too much.
This change avoid putting buffers in local memory if they are not
allocated from a DEVICE_LOCAL heap.
Maybe we can revisit this later if i915 is better able to deal with
more buffers in local memory.
