add workflow to build and release wheel (#775)

### What this PR does / why we need it?

This is a continuing work of #716.
This PR add workflow to build and release wheel, and also release source
to PYPI.
We have 3 conditions to trigger the workflow:

1. PR to `main` and `*-dev`
2. push to `main` and `*-dev`
3. push tag with name of `v*`

Release to PYPI will only be done under condition 3. Under condition 1
and 2, it will generate .tar.gz and build .whl, upload to github
artifacts but will not release.

update:
Will build .whl and upload to github artifacts with scheduled task.


### Does this PR introduce _any_ user-facing change?
No.

### How was this patch tested?
All triggered conditions are well tested with my fork repo.
