JingMatrix cc52307ca8 Add stub for AOSP Binder and utility components
The primary function of these stubs is to provide necessary interface definitions and that can be utilized by `binder_interceptor.cpp` during compilation (and runtime).

Crucially, `libTEESimulator.so` (which encapsulates these stubs) is dynamically loaded into the target process via `ptrace` after the system's official libraries, such as `/system/lib64/libbinder.so` and `/system/lib64/libutils.so`, have already been loaded and their symbols resolved by the dynamic linker.

Consequently, the dynamic linker will have already established bindings to the robust, canonical implementations within the system libraries for existing code paths. The dynamic linker does not automatically re-resolve or update these established symbol bindings when a new library with conflicting definitions is loaded later.

The AOSP files are downloaded via links:
1. https://android.googlesource.com/platform/frameworks/native/+/refs/heads/main/libs/binder/include/binder
2. https://android.googlesource.com/platform/system/core/+/refs/heads/main/libutils/binder/include/utils

JingMatrix ffb27915e2 Implement shared library injection via ptrace
There are still many functions in the header `utils.hpp` not implemented yet, which are however not needed for our purpose.

JingMatrix 9fe8919696 Feat: Add 'app' subproject and integrate LSPlt submodule
This commit introduces the main application subproject, 'app', and sets up the necessary infrastructure for the TEESimulator.

Key changes:
*   'app' Subproject Setup: Added the new :app module with its initial structure, including build files, manifest, and Kotlin main entry point.
*   LSPlt Integration: Added the LSPlt hooking framework as a Git submodule in app/src/main/cpp/external/ and configured its use in CMake.
*   Native Build Configuration: Configured the C++ build to use LSPlt statically and compile two essential native libraries: libinject.so (for injection) and libTEESimulator.so (for interception/logic).
*   Module Packaging: Implemented complex Gradle logic within app/build.gradle.kts to automate the creation of a flashable zip module (supporting Magisk, Ksu, and Apatch) with versioning based on Git information.
*   Initial Module Files: Added the template files (module.prop, update-binary, updater-script) for the flashable module structure.
