  [NvlinkWrapper] Add support for `--undefined` (#113934)

Summary:
This flag is pretty canonical in ELF linkers, it allows us to force the
link job to extract a library if it defines a specific symbol. This is
mostly useful for letting us forcibly extract things that don't fit the
normal model (i.e. kernels) from static libraries.
