nir/lower_samplers: don't assume a deref for both texture and sampler srcs
After commit "nir: Use derefs in nir_lower_samplers"
(75286c2d083cdbdfb202a93349e567df0441d5f7) assumes one deref for both
the texture and the sampler. However there are cases (on OpenGL, using
ARB_gl_spirv) where SPIR-V is not providing a sampler, like for
texture query levels ops. Although we could make spirv_to_nir to
provide a sampler deref for those cases, it is not really needed, and
wrong from the Vulkan point of view.
This patch fixes the following (borrowed) tests run on SPIR-V mode:
arb_compute_shader/execution/basic-texelFetch.shader_test
arb_gpu_shader5/execution/sampler_array_indexing/fs-simple-texture-size.shader_test
arb_texture_query_levels/execution/fs-baselevel.shader_test
arb_texture_query_levels/execution/fs-maxlevel.shader_test
arb_texture_query_levels/execution/fs-miptree.shader_test

arb_texture_query_levels/execution/vs-miptree.shader_test
arb_texture_query_levels/execution/vs-nomips.shader_test

v2: merge lower_tex_src_to_offset and calc_sampler_offsets together,
update texture/sampler index and texture_array_size directly on
lower_tex_src_to_offset (Jason)
v3: clarify one comment (Jason)
