spirv: fix lowering of OpGroupNonUniformAllEqual

It should rely on the source type, not on the return type which
is always a boolean anyways, so vote_feq was never selected. For
OpSubgroupAllEqualKHR it's always an integer comparison.

This fixes some VK_KHR_shader_subgroup_extended_types tests with RADV.
