Adding some convenience API for ConstraintLayout

It's now possible to apply the same constraints to multiple references
at a time.

Within a ConstraintSet users can also create multiple references and
assign them using destructuring declarations. Since this can be an error
prone pattern, added a lint check to verify that given parameters match
the assigned variables.

Relnote: "Apply constraints to multiple elements with `constrain(box,
button, text)`.
In Constraintsets, it's now possible to create multiple references: `val (box, text, button) = createRefsFor(\"box\", \"text\",\"button\")`. Within a ConstrainScope, you may now intuitively set a fixed dimension with Dp.asDimension: `width = 10.dp.asDimension`. "
