glsl: allow bindless samplers/images as vertex shader inputs
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."
