By this patch, an experimental shared-everything modules linking is supported, typically
user could use the feature to dlopen a wasm/aot module, then get the funcref by dlsym, and
call the target function by call indirect instr. Of course, a dlclose is supported too.
Currently, root module could be a regular module, wasi module, or AssemblyScript module;
dependency module MUST be a module built followed the proposal "dynamical linking", that means
it should contain a new dylink section and no mem allocator function exported. User could
get it by clang or emcc. New iwasm switch --enable-dopen is used for enabling the feature and
choosing the launch mode. see the iwasm -h for details.
Multiple modules feature is not well tested, there should be some cases not covered.

Apply clang-format for core/iwasm/include, core/iwasm/common and
core/iwasm/aot files.
Update spec cases test script:
- Checkout latest commit of https://github.com/WebAssembly/spec
- Checkout main branch but not master of https://github.com/WebAssembly/threads
- Update wabt to latest version
And update source debugging document.

In some platforms, allocating memory with size 0 may return NULL but not an empty memory block, which causes runtime load, instantiate or execute wasm/aot file failed. We add checks to try to avoid allocating memory in runtime if the size is 0. And in wasm_runtime_malloc/free, output warning if allocate memory with size 0 and free memory with NULL ptr.
Also fix some coding style issues, fix handle riscv32 ilp32d issue, and fix several wasm-c-api issues.
