Paulo Zanoni 904c9d6464 brw: add a NOP in between WHILE instructions on LNL
This is a workaround that is still in progress, see HSD 22020521218.
If we don't have these NOPs we may see rendering corruption or even
GPU hangs.

While we still don't fully understand the issue from the hardware
point of view, let's have this workaround so we can pass CTS and move
things forward. If we need to change this later, we can. Besides, the
impact is minimal. Shaderdb/fossilize report no changes for this
patch.

On our Blackops trace, the lack of this patch causes corruption in fog
rendering (rectangles where fog was supposed to be shown don't show
the fog).

On dEQP-VK.graphicsfuzz.cov-array-copies-loops-with-limiters, without
this patch we get a GPU hang.

Backport-to: 24.2
Testcase: dEQP-VK.graphicsfuzz.cov-array-copies-loops-with-limiters
