Refactor the creation of unresolved objects
...
Create unresolved objects only for objects in the xref table (except during
parsing of the xref table). Do not add indirect nulls into the the object
cache as the result of a cache miss during a call to getObject except
during parsing or creation/updating from JSON. To support this behaviour,
add new private methods getObjectForParser and getObjectForJSON.
As a result of this change, dangling references are treated as direct nulls
rather than indirect nulls.

In QPDFParser constructor add add parameter parse_pdf
...
Prepare for treating indirect references differently depending on whether
we are parsing a PDF file (in which case reference to objects not in the
xref table are null even if they are in the object cache) or whether parse
from user code (in which case an indirect reference can refer to a user
created object).

libtests: include cstdint for GCC 15
...
GCC 15 starts to no longer include this by default, requiring it to be
explicitly included.
Error message:
libtests/cxx11.cc:75:16: error: ‘uint8_t’ was not declared in this scope
75 | check_size<uint8_t>(1, false);
| ^~~~~~~
libtests/cxx11.cc:10:1: note: ‘uint8_t’ is defined in header ‘<cstdint>’; this is probably fixable by adding ‘#include <cstdint>’

+++ |+#include <cstdint>
