The failure was observe from a nightly VK-CTS run:
https://github.com/shader-slang/slang/actions/runs/12271349271

It appears that this regression is from
#5807

The PR adds error reporting on unrecognized layout qualifiers, so it is expected to break glsl code that contains layout that slang doesn't know about.

We need to decide whether we want to disable those failing tests or fix the issue on Slang side.

The error message is following,

Test case 'dEQP-VK.ubo.2_level_array.std140.row_major_mat2.vertex'..
test.slang.vert(9): error 31217: GLSL layout qualifier is unrecognized or requires assignment
layout(set = 0, binding = 0, std140, row_major) uniform Block
                                     ^~~~~~~~~

It appears that row_major is not recognized by Slang.

I am going to disable the failing tests for now and we will keep track of the issue here.

12 VK-CTS tests are disabled.
We should re-enabled them when we properly support row_major layout keyword.

I was looking at the first 12 failures but it turned out that there were total of 812 failing tests for the same reason.
Disabling the rest of the failing tests.
