Milestone sidebar widget
What does this MR do?
Uses generic dropdown sidebar widget (introduced for epics here: !62168 (merged)) for milestones.
The diff looks quite large because we're moving sidebar_dropdown_widget.vue from EE (previously supporting epics and iterations) to CE (because we now support milestones). Very few changes are made to this component to add support of milestones and make sure iterations and epics are mentioned only in EE. I pointed out those changes on the diff to ease the review process.
This MR only uses the component on Issue boards (behind :graphql_board_lists feature flag) , future iterations will use this component on Issue and Merge Request pages.
