CVE-2023-0614 ldb: Add function to take ownership of an ldb message
Many places in Samba depend upon various components of an ldb message
being talloc allocated, and hence able to be used as talloc contexts.
The elements and values of an unpacked ldb message point to unowned data
inside the memory-mapped database, and this function ensures that such
messages have talloc ownership of said elements and values.
