libdw: Handle DWARF5 immutable, packed and shared in dwarf_peel_type.

Also update the documentation to explain that any type alias or modifier
that doesn't modify, change the structural layout or the way to access
the underlying type is peeled. Explicitly mention pointer and reference
types as examples of modifiers that don't obey that rule and so aren't
peeled.
