codecs: add native build scripts for libvpx/opus/speex + fix CMake includes
- scripts/build-native-codecs.sh: cross-compile libvpx, opus, speex for Android ABIs (arm64-v8a, armeabi-v7a, x86_64) using NDK clang with -fPIC - scripts/android-ndk.sh: NDK root detection helper - scripts/native-build-cache.sh: ccache detection helper - scripts/init-third-party-submodules.sh: init codec submodules - scripts/ensure-gradle-wrapper.sh: gradle wrapper sanity check - scripts/adb-reconnect.sh: ADB device discovery helpers - ndk/CMakeLists.txt: per-ABI include dirs for opus/ and speex_config_types.h Co-authored-by: Cursor <cursoragent@cursor.com>
