…ance#622)

Implement more wasm-c-api APIs to support Envoy integration:
- sync up with latest c-api definition
- change CMakeLists to export necessary headers and install the static library of iwasm
- enable to export tables and memories
- support memorytype and tabletype APIs
- update wasm-c-api sampels
- enable to export importtype APIs

And refine bazel scripts for sample XNNPACK workload, add license headers for sample simple.
