Collapse the PipelineAssetsRoleDefaultPolicy into a single up-front policy that
doesn't grow per-asset. This relaxes some of the permissions in exchange for
avoiding an O(N) policy size.

fixes #9316

Testing notes: Successfully deployed a pipeline with 49 assets (25 file assets and 24 docker assets). 50 assets is the limit for a single stage of the pipeline. To scale out past 50 assets, we will need to segment the assets pipeline stage into multiple stages. I'm considering that out-of-scope for this bugfix.
