style: apply fixes for eslint issues [cw-3590] (#10210)

These fixes are all auto generated and can be merged directly

Fixes the following issues

1. Event used on components should be hypenated
2. Attribute orders in components
3. Use `unmounted` instead of `destroyed`
4. Add explicit `emits` declarations for components, autofixed [using
this
script](https://gist.github.com/scmmishra/6f549109b96400006bb69bbde392eddf)


We ignore the top level v-if for now, we will fix it later
