Implement support for module symbols (#475)

Browse Source 
* **New Features**
  - Adds module symbol support and per-module symbol tables, including LVGL symbol exports moved into a dedicated table.
* **API**
  - Adds symbol-resolution APIs and an accessor to enable dynamic lookup between modules.
* **Bug Fixes / Chores**
  - Explicitly initializes module symbol pointers across device and platform modules to avoid uninitialized state.
* **Tests**
  - Updates tests to account for symbol pointer initialization.
