V8 14.9.207.39 built from a1e3b5ae1e8d036491e85ada39a7ccffe937444a.
Built against Android NDK r29; it must match the
NDK the Android runtime is built with, because libc++ is only ABI-compatible
with itself across a static link.
Patches applied: v8_resurrecting_finalizers.patch (restores
WeakCallbackType::kFinalizer), android_build.patch (API 21 floor,
selectable android_ndk_root, macOS host support).
