Add a workflow to create release build (#217)

This CL setup a workflow to create a release build.

Below is the steps to create a release:
1. submit all changes to master branch
2. create a RELEASE.md file under the root directory, the "RELEASE.md" can be created via github's draft new release text page
3. submit RELEASE.md to master branch
4. create a release tag, a release tag is like "v[0-9]+.[0-9]+.[0-9]+", this can be done locally: git tag <tag_name>
5. push the tag: git push <repo> tag <tag_name>
6. the work flow will be triggered

This workflow can also be manually triggered to create a release for older versions.

The workflow shall be further improved so that we can create the release on the github webpage and let it trigger the release build.

* Add a workflow to create relase build.

* Addressed review comments.

* Use clang/clang++ to build release binaries.
