glsl: allow bindless samplers/images as vertex shader inputs

Browse source 
From section 4.3.4 of the ARB_bindless_texture spec:

   "(modify third paragraph of the section to allow sampler and
    image types) ...  Vertex shader inputs can only be float,
    single-precision floating-point scalars, single-precision
    floating-point vectors, matrices, signed and unsigned integers
    and integer vectors, sampler and image types."

v3: - update spec comment formatting
