Remove unnecessary functions and implement more APIs: - wasm_##name##same - wasm##name##as_ref - wasm_ref_as##name## - wasm_ref_delete - wasm_module_validate - wasm_table_get/set/size - wasm_memory_size - wasm_config_new - wasm_foreign_new And add more wasm-c-api samples, update the related documen, add more CI rules.
