Fix QNN Android AAR build (#18577)

manuelcandales · web-flow · commit 6b2537d93015 · 2026-03-30T11:06:48.000-04:00
Add missing attention_sink_rope_runner.cpp to Android JNI build

This fixes a linker error when building libexecutorch_jni.so for the QNN
flavor of the Android AAR. The QNN llama runner sources
(lhd_token_generator.cpp, token_generator.cpp, prompt_processor.cpp,
runner.cpp) reference AttentionSinkRopeRunner but its implementation
wasn't being compiled into the JNI library.
