Rename executorch-llama.aar to executorch.aar

Let's use a uniform name. It's easier to maintain and less error prone.

It won't cause BC issue. All renaming are happening within this repo,
this version. For user apps, after they download or build the AAR, they
can rename in their build.gradle.kts.

Test:
1. `sh examples/demo-apps/android/LlamaDemo/download_prebuilt_lib.sh` run twice!
2. `sh build/build_android_llm_demo.sh`
3. `sh examples/demo-apps/android/LlamaDemo/setup.sh`
4. `sh examples/demo-apps/android/LlamaDemo/setup-with-qnn.sh`
