This commit refactors the AOT loader in `aot_loader.c` to support compatible versions of the AOT_CURRENT_VERSION constant. Previously, the loader only accepted the exact AOT_CURRENT_VERSION value, but now it also accepts version 3. This change ensures that the runtime can load modules AoT-compiled with different versions of wamrc as long as they have compatible AOT_CURRENT_VERSION values. Related to #3880.
