move vue and vue-calendar-heatmap to webpack (#10188)

- unvendor vue and vue-calendar-heatmap
- remove unused moment.js leftover from previous heatmap version
- ensure webpack loads the full version of vue
- fix vue devmode warning related to 'searchLimit' type

I wanted to name the chunk heatmap.js but adblockers don't like that
