[K/N] Add opt-in flag to use debug info from native libs

Unfortunately, llvm removes full debug info from module on any error.
Different version debug info in bitcode is not always compatible, also
it adds this debug info additional requirements on generated debug info.

So this feature is quite unstable and shouldn't be enabled by default,
although it has almost no downsides when worked correctly.
