perf($compile): do not use deepWatch in literal one-way bindings

Avoiding deep watchers for array/object literals will improve watcher
performance of all literals passed as one-way bindings, especially those
containing references to large/complex objects.

BREAKING CHANGE:
Previously when a literal value was passed into a directive/component via
one-way binding it would be watched with a deep watcher.

For example, for `<my-component input="[a]">`, a new instance of the array
would be passed into the directive/component (and trigger $onChanges) not
only if `a` changed but also if any sub property of `a` changed such as
`a.b` or `a.b.c.d.e` etc.

This also means a new but equal value for `a` would NOT trigger such a
change.

Now literal values use an input-based watch similar to other directive/component
one-way bindings. In this context inputs are the non-constant parts of the
literal. In the example above the input would be `a`. Changes are only
triggered when the inputs to the literal change.
