Especially when GC is enabled, a valid item of `module->types` needs additional
checks before casting to WASMFuncType.
Also, avoid overflowing if reftype_map_count is 0.
Additionally, correctly set IN_OSS_FUZZ based on CFLAGS_ENV for sanitizer
configuration. Update ASan and UBSan messages for clarity in non-oss-fuzz
environments.
LLVM, by default, disables the use of C++'s built-in Run-Time Type Information.
This decision is primarily driven by concerns about code size and efficiency.
But '-fsanitize=vptr' not allowed with '-fno-rtti'.

CMake Error at CMakeLists.txt:4 (cmake_minimum_required):
Compatibility with CMake < 3.5 has been removed from CMake.
Update the VERSION argument <min> value. Or, use the <min>...<max> syntax
to tell CMake that the project requires at least <min> but has been updated
to work with policies introduced by <max> or earlier.
Or, add -DCMAKE_POLICY_VERSION_MINIMUM=3.5 to try configuring anyway.
```
* Update CMakeLists.txt of fuzzing
- enable software bound-check
- enable wasi
- disable libc builtin and multiple modules
* Fix off-by-one error in result offset calculation for function calls
- possible integer overflow in adjust_table_max_size:
unsigned integer overflow: 2684354559 * 2 cannot be represented in type 'uint32'
- limit max memory size in wasm_runtime_malloc
- add more checks in aot loader
- adjust compilation options
- Add a marco to limit the maxi allocable memory size of fuzz test to
2GB to avoid libFuzzer out-of-memory
- Check global type in load_global_import and load_global_section
