Replace the shader-based R/B swap with the blob driver's approach:
use A8R8G8B8 as the texture format so the sampler correctly interprets
the BGRA bytes the PE writes, and perform R<->B conversion at the
CPU boundary during transfer blits (tiled<->linear copies).
The R/B swap is gated by an in_transfer_blit context flag so that
GPU-internal blits (e.g. glBlitFramebuffer) operating on data already
in BGRA byte order are not affected.
For RB_SWAP formats, skip the texture shadow shortcut to ensure the
blit engine path is used, which handles the R/B swap correctly for
both reads and writes.

Add a helper that returns the BGRA pipe format for a given RGBA pipe
format when the PE uses RB_SWAP. This is needed to pack clear colors
in the byte order the hardware actually stores.
Also fix translate_pe_format_rb_swap() to return 0 for formats with
PE_FORMAT_NONE, avoiding false positives on texture-only formats.

It was already computed in brw_shader::assign_curb_setup() so we can use it
in brw_assign_urb_setup().
There was a mismatch between assign_curb_setup() and brw_assign_urb_setup() when
push_sizes were not multiple of REG_SIZE, the first one was aligning every
push_sizes before sum it, while brw_assign_urb_setup() was only aligning the sum
of all push_size.
By luck the only places that did not had a push_size aligned to REG_SIZE only
had one push_size, so this was not an issue.
So here also fixing this mismatch and adding an assert to caught any future

These tests were previously skipped because they contain dynamic loops
in the VS, which can cause GPU resets on VC4. However, (1) the only
tests that cause GPU resets are the ones that have divergent loops and
(2) now, the compiler is able to fail shader linking when it finds
divergent loops.
Therefore, allow tests with non-divergent loops to run on the CI and
add tests with divergent loops to the fail list.

On V3D 4.2 (Raspberry Pi 4), there is a hardware bug where the binner
can trigger a GPU reset in some situations where primitives are
discarded, such as due to primitive restarts.
The way to avoid this is to force the binner to do always something, by
emitting the proper CL. In this case we decided to always set point
size, as it is a very simple and fast operation.
This fixes resets caused by
