 libdl: Do not access the ELF file while the allocator is locked.

 - Load symbols before allocation.
 - Parse reloc records and place any reloc recs in a cache to use
   while the allocator is locked.
 - Relocate symbols after section allocation.
 - Split section loading into allocation/locating and loading.
 - Update all arch back-ends with a new reloc interface to control
   tramp handling.
 - Add `-a` and `-t` to the object list shell command.

 Closes #3741
