* fix: disable unsigned integer overflow sanitization in build configurations
FYI: from https://clang.llvm.org/docs/UndefinedBehaviorSanitizer.html
`-fsanitize=unsigned-integer-overflow`: Unsigned integer overflow, where the result of an unsigned integer computation cannot be represented in its type. Unlike signed integer overflow, this is not undefined behavior, but it is often unintentional. This sanitizer does not check for lossy implicit conversions performed before such a computation.
It brings a more common question: which is better, pre-additional-check or post-additional-check to fix a potential unsigned integer overflow? A pre-additional-check involves using a check to prevent integer overflow from the very beginning. A post-additional-check involves using a check after addition to see if there is an overflow.
In this project, post-additional-checking is widely used. let's follow the routine.
for performance sensitive logic, use __builtin_add_overflow etc. provide something like 9a5622791e/lib/platform.h (L176-L191) and encourage the use of them.

The local fuzzing server is a feature that has not been used for a long
time and is currently unmaintained. Temporarily remove it from the
codebase, and restore it when needed.
* Fix vector growth check and typos in core (#9)
* Fix resource cleanup in memory and running modes tests (#10)
* Add end of file empty line in wasm_running_modes_test.cc
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.
```
- Enhance wasm mutator fuzz tests by adding export function execution and random value generation
- Use --fuel to limit loop size
- Use predefined values and enhance argument logging in execution
* 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
