feat(lint): add type-aware rules

[johnsoncodehk]

Exploration move to tsslint to use type-aware rules in a high-performance manner.

I tested all type-aware rules of typescript-eslint and added the ones with no friction from Vue core:

• await-thenable
• require-await (As suggestion instead of error, since the async keyword can changes code behavior.)
• consistent-type-exports
• no-unnecessary-type-arguments
• no-unnecessary-type-assertion
• non-nullable-type-assertion-style

is this comment referring to the now removed assertion?

[johnsoncodehk]

I'm not sure what this comment means. This comment was added in b685805, I reset to that commit and confirmed that the type of children[0] is not SlotOutletNode, so I think this comment may be not related to the removed assertion.
