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.
