[FR] Provide static libc++ without exception

**Is your feature request related to a problem? Please describe.**
Once using things that use exceptions, such as `new` and `unordered_set`, the exception will be included, which means a very huge size increase (~200KB per so file).

It is unacceptable the size of my so has increased from 14KB to 200KB only because I use `new`. Many things in the C++ world uses exception inside, it's impossible to avoid exceptions if we want to use C++. The option `-fno-exceptions` will not work of course since exceptions are included in the static library libc++ rather than the user's codes.

Crashing is so common in Android, and most times exception does not help. Use `new` as the example, if `new` (malloc inside) fails, it's obvious that throw an exception here does nothing help.

**Describe the solution you'd like**
Provide libcxx compiled with `-D_LIBCPP_NO_EXCEPTIONS` and `-D_LIBCPP_NO_RTTI` (and libcxxabi compiled with `-D_LIBCXXABI_NO_EXCEPTIONS`), then provided an option to let the user choose whether to use this libcxx or not.

Begin by reviewing how the Android NDK builds and packages libc++ and libc++abi, focusing on the requested no-exceptions and no-RTTI compile definitions. Determine how users could select a static variant without exceptions; done means the variant is provided alongside the existing option and its size impact can be verified.
