glsl: allow bindless samplers/images inside interface blocks

Browse Source 
From section 4.3.7 of the ARB_bindless_texture spec:

   "(remove the following bullet from the last list on p. 39, thereby
    permitting sampler types in interface blocks; image types are also
    permitted in blocks by this extension)"

    * sampler types are not allowed

v3: - update the spec comment
    - update the glsl error message
