* Run our custom eslint rules using ts-node
Use `ts-node` to run our custom eslint rules. This lets us delete the pre-compiled js. It also means you can don't have to compile the rules while editing them
As part of this change, I've also switched us to using an eslint plugin instead of a rulesDir. This is now the preferred way to ship custom rules
* Fix two more disables
* Move ts-node to project root
* Enable transpileOnly
* Build VS Code using TS 4.4
* Remove usages of deprecated `ClientRectList`
* Add any casts for missing `caretRangeFromPoint`
* Add temporary any casts for `zoom` css propery
This non-standard css property no longer exists in lib.dom.d.ts
* MouseWheelEvent -> WheelEvent
* Pick up new TS nightly
