  [ORC] Mangle Dlfcn CI names as C (fixes MachO dlopen lookup) (#225392)

The __orc_rt_jit_dl{open,update,close}_wrapper functions are C symbols
in the ORC runtime, so on Darwin their linker names carry a leading
underscore. The controller must resolve them under the C-mangled name.
The original LLJIT code did this via mangleAndIntern; the Proxy
conversion (#224881) used Verbatim by mistake, so on MachO the lookup
searched for the unmangled name and failed ("Symbols not found:
__orc_rt_jit_dlopen_wrapper"). Flip the Dlfcn descriptors to C to
restore the mangling. No runtime change is needed -- compiler-rt already
exports these as C symbols.
