LibPDF: Store indirect value refs in Value objects

Browse source 
IndirectValueRef is so simple that it can be stored directly in the
Value class instead of being heap allocated.

As the comment in Value says, however, in theory the max bits needed to
store is 48 (16 for the generation index and 32(?) for the object
index), but 32 should be good enough for now. We can increase it to u64
later if necessary.
