- Replace sys.exit with exceptions for better error handling in test assertions
- Update exception handling in compile_wast_to_wasm to catch all exceptions
- Improve error messages and logging
- Use `--ignore-whitespace` option for git apply in spec_test function
- Use raw string notation for regex patterns. *The "SyntaxWarning: invalid escape sequence" in Python The warning has been upgraded to SyntaxWarning since Python 3.12, and it is expected to become a SyntaxError in future versions.*
- Add early return for non-loadable AOT compilation to prevent unnecessary assertions
- Redirect stderr to stdout in test_case for unified output
- Update `create_tmpfiles()` to improve clarity and handling of temporary files
Last bit missing from #3206: demangling of function names (useful for wasm
generated from Rust for instance) using `llvm-cxxfilt`.

Update the `addr2line` script so that:
- line info is printed in a more convenient format, e.g.
```
0: c
at wasm-micro-runtime/test-tools/addr2line/trap.c:5:1
1: b
at wasm-micro-runtime/test-tools/addr2line/trap.c:11:12
2: a
at wasm-micro-runtime/test-tools/addr2line/trap.c:17:12
```
similar to how Rust prints stack traces when there's a panic. In an IDE, the user
can conveniently click on the printed path and be redirected to the file line.
- a new `--no-addr` argument can be provided to the script
It can be used in fast interpreter mode (that is not supported by the script otherwise)
or with older wamr versions (where the stack trace only had the function index info
and not the function address). In that case, `wasm-objdump` is used to get the function
name from the index and `llvm-dwarfdump` to obtain the location info (where the line
refers to the start of the function).
- Address values in call stack dump are relative to file beginning
- If running under fast-interp mode, address values are relative to
every pre-compiled function beginning, which is not compatible
with addr2line
Implement the GC (Garbage Collection) feature for interpreter mode,
AOT mode and LLVM-JIT mode, and support most features of the latest
spec proposal, and also enable the stringref feature.
Use `cmake -DWAMR_BUILD_GC=1/0` to enable/disable the feature,
and `wamrc --enable-gc` to generate the AOT file with GC supported.
And update the AOT file version from 2 to 3 since there are many AOT
ABI breaks, including the changes of AOT file format, the changes of
AOT module/memory instance layouts, the AOT runtime APIs for the
AOT code to invoke and so on.
