feat($compile): do not interpolate boolean attributes, rather evaluate them

So that we can have non string values, e.g. ng-value="true" for radio inputs

Breaks boolean attrs are evaluated rather than interpolated

To migrate your code, change: <input ng-disabled="{{someBooleanVariable}}">
to: <input ng-disabled="someBooleanVariabla">


Affected directives:

* ng-multiple
* ng-selected
* ng-checked
* ng-disabled
* ng-readonly
* ng-required
