liang.he f118492b1d Add integer overflow check for some indices in wasm/aot loader (#3579)
Check whether the indices overflow UINT32_MAX or not for:
- import function count + function count
- import global count + global count
- import tag count + tag count

This PR fixes the issue reported by Oss-fuzz test (#69920).
