Source NDK installer and use NDK_HOME

Source the NDK install script in CI (AppVeyor and GitHub Actions) so its environment is applied. .ci/install_ndk.sh now exports NDK_HOME and ensures a trailing newline. In src/forge/build.py, add logic to detect NDK_HOME and re-point missing compiler/binutils to the NDK toolchain prebuilt bin directory so Android build archives that reference embedded NDK paths work in CI. Also uncomment build.script_env in the pydantic-core recipe to set _PYTHON_SYSCONFIGDATA_NAME.
