Improve wasm-c-api instantiation-time linking (#1902)
Add APIs to help prepare the imports for the wasm-c-api `wasm_instance_new`: - wasm_importtype_is_linked - wasm_runtime_is_import_func_linked - wasm_runtime_is_import_global_linked - wasm_extern_new_empty For wasm-c-api, developer may use `wasm_module_imports` to get the import types info, check whether an import func/global is linked with the above API, and ignore the linking of an import func/global with `wasm_extern_new_empty`. Sample `wasm-c-api-import` is added and document is updated.
