**Summary** Install new `@apply_metadata()` on HTML and remove decorators from delegating partitioners EPUB, MD, ORG, RST, and RTF. **Additional Context** - All five of these delegating partitioners delegate to `partition_html()` so they're something of a matched set. EML and MSG also partially delegate to HTML but that's a harder problem (they also delegate to all other partitioners for attachments) that we'll address a couple PRs later . - Replace use of `@process_metadata()` and `@add_metadata_with_filetype()` decorators with `@apply_metadata()` on `partition_html()`. - Remove all decorators from delegating partitioners; this removes the "double-decorating".
