Fixes 'nir_tex_src_coord' param was provided to NIR 'txf' operation as a vec3 for TEXTURE_1D_ARRAY target, causing an assert. Only following targets require vec3: TEXTURE_2D_ARRAY, TEXTURE_3D, TEXTURE_CUBE, TEXTURE_CUBE_ARRAY. The rest must use vec2.
Packing layer value into Y-coordinate the same way it was done in 'create_fs' in commit 2bf6dfac.
Fixes: a01ad311 ("st/mesa: Add NIR versions of the PBO upload/download shaders. ")
