libcxx-compat: fix llvmorg-21-init-18351-gfcc09b6f0267:

[libc++] Fix std::make_exception_ptr interaction with ObjC (#135386)

  Clang treats throwing/catching ObjC types differently from C++ types,
  and omitting the `throw` in `std::make_exception_ptr` breaks ObjC
  invariants about how types are thrown/caught.

  Fixes #135089

  Co-authored-by: Louis Dionne <ldionne.2@gmail.com>

Only use lambdas when in !defined(_LIBCPP_CXX03_LANG), so this will
compile with clang 18 and lower, in C++03 mode and earlier.
