vkd3d-shader/hlsl: Introduce hlsl_deref_is_lowered() helper.

Browse Source 
Some functions work with dereferences and need to know if they are
lowered yet.

This can be known checking if deref->offset.node is NULL or
deref->data_type is NULL. I am using the latter since it keeps working
even after the following patches that split deref->offset into
constant and variable parts.
