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.
