ci(rh-shield-operator): enhance operator release pipeline

The old pipeline would simply build and push the operator and bundle
images. This was a start, but left numerous manual steps to get the
Operator itself certified. The changes in this PR add the following
enhancements to the pipeline.

1. Generate the Bundle content in the pipeline
  a. Run the 'make bundle' command in the pipeline as opposed to
     requiring it be run beforehand.
  b. Since the pipeline guarantees the operator image itself will be
     built and pushed before the bundle is generated, we can set
     USE_IMAGE_DIGESTS=true when running 'make bundle' to include
     the image checksums in the bundle. This is a requirement for
     certification.
  c. The newly generated bundle content will be 'massaged' to
     include the annotations required for certification that are not
     created by the operator-sdk.
2. Trigger preflight certification
2. Decouple the various builds and certification steps that aren't related
