libdl: Add support for large memory programs
- Add trampolines to support relocs that are out of range on
support architectures.
- Support not loading separate text/data sections in an object
file if the symbol provided in the section is a duplicate.
A base image may have pulled in part of an object and another
part needs to be dynamically loaded.
- Refactor the unresolved handling to scale to hundreds of
unresolved symbols when loading large number of files.
Updates #3685
