Support ESLint's --fix-type option

[macklinu]

ESLint v5.9.0 introduced the --fix-type flag, which allows for people to fix issues of a certain type.

To support this feature, we will want to update our fixable rules to use a meta.type property that is one of problem, suggestion, or layout.

Whenever someone gets to this, make sure to enable https://github.com/not-an-aardvark/eslint-plugin-eslint-plugin/blob/master/docs/rules/require-meta-type.md as well

The typescript utils require this to be defined, so this'll be fixed by completing the migration tracked in #256
