Issue #3783: CI Check Builds

Adding workflow for Github hosted CI check builds. Supports all three
supported platforms with all runtime languages except swift.

Also, includes cpp native builds across all supported platforms i.e.
independent on the test run builds.

Every congiguration build generates an artifact (archive of the entire
repository) and is uploaded as a result of the build (regardless of
success or failure).
