Support muti-module for AOT mode (#2482)

Browse Source 
Support muti-module for AOT mode, currently only implement the
multi-module's function import feature for AOT, the memory/table/
global import are not implemented yet.

And update wamr-test-suites scripts, multi-module sample and some
CIs accordingly.

# WAMR MULTI-MODUEL SAMPLE
**WAMR supports *multi-module* in both *interpreter* mode and *aot* mode.**
Multi-modules will determine the running mode based on the type of the main module.
``` shell
$ mkdir build
$ cd build
$ cmake ..
$ make
$ # It will build multi-module runtime and
$ # wasm file under the ./build .
$ # If you have built wamrc,
$ # aot file will also genrate.
$ ./multi-module mC.wasm
$ ...
$ ./multi-module mC.aot
