  Prototype selection API for shadow DOM

Reviewed by Wenson Hsieh.

Prototype Selection.prototype.getComposedRanges and Selection.prototype.direction as spec'ed here:
https://w3c.github.io/selection-api/#dom-selection-getcomposedrange
https://w3c.github.io/selection-api/#dom-selection-direction

One notable difference is that we support returning a sequence of StaticRanges as opposed to
a single range so the method name is accordingly getComposedRange"s".
