  Add support for mach-o symbol stubs. (#225155)

This patch add support for making symbols from the symbol stubs in
mach-o files. Symbol stubs are found in sections that whose type is
S_SYMBOL_STUBS and using these setions along with the indirect symbol
table, we can make symbols for the PLT entries for external functions.
Some crashes occur in these stubs and previous to this fix those
addresses might be incorrecty associated with the last real symbol from
the symbol table and cause confusion and incorrect stack attributions in
symbolication workflows.
