When building python3.14 user should be forced to upgrade to ndk_target_24 and api_target_24 instead of throwing an error that is not understood.

Descripción
I got this error while building python3.14
```c
/home/kengo/PycharmProjects/parkkly/.buildozer/android/platform/build-arm64-v8a_armeabi-v7a/build/other_builds/python3/arm64-v8a__ndk_target_23/python3/Python/remote_debugging.c:48:19: error: call to undeclared function 'pwritev'; ISO C99 and later do not support implicit function declarations [-Wimplicit-function-declaration]
48 | written = pwritev(handle->memfd, local, 1, offset);
| ^
```
After some research I discovered that:
> This means the compiler encountered a call to pwritev() but couldn't find its prototype.
In modern C (C99+), calling undeclared functions is no longer allowed.
And it could be fixed by patching `Python/remote_debugging.c` to include
```c
#include
```
Which I think should be a good option to still support lower android versions.
But then again I discovered that:
> Android NDK only supports pwritev() from API level 24 (Android 7.0, Nougat) and above.
Guía de contribución
Línea de trabajo
Comienza con Python/remote_debugging.c y reproduce la compilación de python3.14 usando ndk_target_23 y api_target_23. Traza dónde gestiona python-for-android estos ajustes de destino; se considera terminado cuando la compilación requiere claramente ndk_target_24 y api_target_24 en lugar de emitir el error inexplicado de pwritev().
