Merge branch 'feat/developer/9119-marker-update-spec-epic-ldml' into feat/core/9119-marker-core-epic-ldml

- fix a logic err in vars - premature optimization was skipping when we had markers but no other vars
- update marker output in keys, including to and longpress.  TODO-LDML still do not handle markers in lists (longpress, multitap, or flicks). The tests are there but commented out.
