From section 4.1.7 of the ARB_bindless_texture spec:
"Samplers can be used as l-values, so can be assigned into and
used as "out" and "inout" function parameters."
From section 4.1.X of the ARB_bindless_texture spec:
"Images can be used as l-values, so can be assigned into and
used as "out" and "inout" function parameters."
v4: - invert the logic
v3: - update spec comment formatting
- keep the read_only check
