  [MachO LLD] Respect -all_load with --start-lib --end-lib style archives (#93993)

The -all_load flag is intended to force the linker to load all lazy members, but doesn't do so if the archive is specified with --start-lib, --end-lib flags. The `-all_load` flag is global, that is it can be placed anywhere in the linker invocation, and it affects the load behavior of all conventional archives listed. Unlike ELF's --whole-archive, the user need not necessarily have access to the entire linker invocation to reasonably make use of the flag. The user can supply `-all_load` to a build system without inspecting the rest of the linker invocation.

To make the behavior of `--start-lib` style archives consistent with regular archives, this patch makes it so that -all_load also applies in this case.
