Lint: Add eslint import plugin (#5955)

## Summary

Adds the linter, turns on the recommended and a few extra rules, fixes
existing violations.

Doesn't prohibit `../../...` imports yet, that'll be it's own PR.

## Changes

- **What**: Consistent and fixable imports
- **Dependencies**: The plugin and parser

## Review Focus

How do you feel about the recommended rules?
What about the extra ones?
[Any

you'd want to turn on?
