ERR is used to indicate internal inconsistencies in vkd3d. Here that's
not the case, we simply have to forward the error condition to the
caller.
This fixes failures on the CI with llvmpipe, because the build we use is
compiled without support for VK_KHR_surface and related extensions.
Fixes output signature normalisation failures in Silent Hill 2 caused by
failure of shader_signature_find_element_for_reg().

The number of components needed for texel offsets is the number of
components needed to address a single image/layer of an array. I.e.,
"coordinate_component_count - 1" for array textures, and
"coordinate_component_count" for non-array textures.
This change will also fix sampling of cube textures with explicit
gradients. Because texel offsets are unsupported for cube textures,
"offset_component_count" is currently 0 for cube textures. However, the
SAMPLE_GRAD handler also uses "offset_component_count" to determine the
number of components needed for the explicit gradients, and SAMPLE_GRAD
is supposed to work with cube textures.
This commit fixes the compilation of shaders in Star Wars Jedi:
Survivor.
