PoC: Move NDK from sentry-java to sentry-native

[markushi]

:scroll: Description

Relevant sentry-native PR: https://github.com/getsentry/sentry-native/pull/944 To make this branch work, you need to publish the sentry-native ndk artifact first:

1. cd sentry-native/ndk
2. ./gradlew :lib:publishToMavenLocal

:bulb: Motivation and Context

Move NDK code over to sentry-native, to make it more testable and robust. So far all looks good, but using sentry.h / linking libsentry.so does not work, as the sentry-native git submodule is not present anymore. However we're using https://github.com/howardpang/androidNativeBundle, which apart from publishing, also allows you to consume .h/.so files: https://github.com/howardpang/androidNativeBundle#3-import-aar

:green_heart: How did you test it?
