Separate GitHub actions workflows

[stefanbotez]

Description of changes:

• GitHub actions workflow currently builds all packages on push and pull request no matter of the package changed
• Separated the GitHub actions workflows to run based on the package changed. It builds the package changed and the packages that depend on that package. There could be some duplication builds if multiple packages are changed in a single pull request, but for most cases it should not be a problem since before including the RIC, building all the other packages took around 1 minute.
