Centralize dependencies and migrate to submodules (#512)

Centralize dependencies and migrate to submodules

Move `apache` and `axml` modules to a unified `external` directory and migrate libxposed API and service interfaces from Maven dependencies to Git submodules.

Included changes:
- Updated .gitmodules with new paths.
- Simplified core.yml CI workflow.
- Updated Gradle project references to use the new directory structure.
- Added documentation for external components.

+# External Dependencies
+
+This directory contains all the external dependencies required to build the Vector framework.
+They are included as git submodules to ensure version consistency and timely updating.
+
+## Native dependencies
+
+-   [Dobby](https://github.com/JingMatrix/Dobby): 
+    A lightweight, multi-platform inline hooking framework. It serves as the backend for all native function hooking (`HookInline`).
+
+-   [fmt](https://github.com/fmtlib/fmt):
+    A modern formatting library used for high-performance, type-safe logging throughout the native code.
+
+-   [LSPlant](https://github.com/JingMatrix/LSPlant):
+    A hooking framework for the Android Runtime (ART). It provides the core functionality for intercepting and modifying Java methods.
+
+-   [xz-embedded](https://github.com/tukaani-project/xz-embedded):
+    A lightweight data compression library with a small footprint. It is used by the ELF parser to decompress the `.gnu_debugdata` section of stripped native libraries.
+
+-   [LSPlt](https://github.com/JingMatrix/LSPlt):
+    A library for PLT (Procedure Linkage Table) hooking. It is used in the `dex2oat` sub-project to bypass a detection point. **Note:** This is included as a submodule for project convenience but is not compiled into the `external` C++ library itself.
+
+## Java libraries
+
+-   [apache/commons-lang](https://github.com/apache/commons-lang):
+    A package of Java utility classes for the classes that are in java.lang's hierarchy. Some classes are renamed and then used to implement the `XposedHelpers` API.
+
+-   [axml/manifest-editor](https://github.com/JingMatrix/ManifestEditor):
+    A a tool used to modify Android Manifest binary file. It is to parse manifestation files of Xposed modules.
