test: expand linting rules around assert w literal messages

Expands the existing restrictions around not using literal messages
to the `not` variants of `strictEqual` and `deepStrictEqual`, and
forbids `assert()` where the second argument is a non-string literal,
which almost always is a mis-typed `assert.strictEquals()`.
