nir: add vs_inputs_dual_locations compiler option
Allows nir drivers to either use a single or dual locations for
vs double inputs.
i965 uses dual locations for both OpenGL and Vulkan drivers, for
now gallium OpenGL drivers only use a single location.
The following patch will also make use of this option when
calling nir_shader_gather_info().
