By binding the token DOM_REFLECT_PROPERTIES_AS_ATTRIBUTES provided by
the dom_renderer module to true in the root injector (i.e. bootstrap()),
all elements whose properties are set by angular will be reflected as
attributes with the prefix "ng-reflect-".

Fixes #2910

NOTE: I expect enforce-format to break since it is broken on master right now. @alexeagle is fixing.

@tbosch I made the change to use string interpolation and to unwrap the prefix string literal from CONST_EXPR. Look good?
