feat(pipelines): Add ability to define fileSystemLocations for a CodePipeline (#24584)

This adds the ability to define fileSystemLocations for CodePipeline.  Currently, there is not a simple way (or any way that I know of) to do this. This will come in handy when e.g. attaching EFS filesystems to CodePipelines.

Closes #24495.
