Reduce use of deprecated Metadata builder method (#124292)
This removes all non-test usage of Metadata.Builder.put(IndexMetadata, boolean) And replaces it with appropriate calls to the equivalent method on `ProjectMetadata.Builder` In most cases this _does not_ make the code project aware, but does reduce the number of deprecated methods in use.
