* feat(api): expose aligned allocation through wasm_runtime_aligned_alloc

Add public API for aligned memory allocation, exposing the existing
mem_allocator_malloc_aligned infrastructure through wasm_export.h.

- Add wasm_runtime_aligned_alloc() API declaration with documentation
- Implement internal helper wasm_runtime_aligned_alloc_internal()
- Add public function with size/alignment validation
- POOL mode only, returns NULL for other memory modes
- Follows wasm_runtime_malloc() patterns for consistency

* fix(tests): resolve memory leak in bh_queue_test_suite and improve message handling
* test(mem-alloc): add tests for freeing read-only and freed pointers
* test(mem-alloc): add tests for huge allocations and OOM scenarios

Fix the warnings and issues reported:
- in Windows platform
- by CodeQL static code analyzing
- by Coverity static code analyzing

And update CodeQL script to build exception handling and memory features.

Implement GC (Garbage Collection) feature for interpreter, AOT and LLVM-JIT (#3125)
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.

Refine aot call_indirect opcode translation (#492)
Re-implement aot call_indirect opcode translation: when calling non-import function, translate it by LLVM call IR to call the function in AOTed code, so as to avoid calling runtime aot_call_indirect API which is much slower. For import function, keep calling aot_call_indirect API due to the possible pointer/string argument conversion.

And add prompt info while app heap is corrupted, change emit_leb to emit_uint32 inter fast-interp to refine footprint.
