fix($rootScope): remove support for a watch action to be a string

BREAKING CHANGE:

Previously, it was possible for an action passed to $watch
to be a string, interpreted as an angular expresison. This is no longer supported.
The action now has to be a function.
Passing an action to $watch is still optional.

Before:

```js
$scope.$watch('state', ' name="" ');
```

After:

```js
$scope.$watch('state', function () {
  $scope.name = "";
});
```

fix(csp): fix autodetection of CSP + better docs

CSP spec got changed and it is no longer possible to autodetect if a policy is
active without triggering a CSP error:

https://github.com/w3c/webappsec/commit/18882953ce2d8afca25f685557fef0e0471b2c9a

Now we use `new Function('')` to detect if CSP is on. To prevent error from this
detection to show up in console developers have to use the ngCsp directive.

(This problem became more severe after our recent removal of `simpleGetterFn`
 which made us depend on function constructor for all expressions.)

test(jqLite): increase timeout and add a label

This test has been flaky on Sauce+IE.
I think 2secs might be not enough for IE sometimes.
chore(travis): enable SL video recording
chore(travis): increase browserNoActivityTimeout

We’ve seen many failures recently because of Karma killing a browser
after browserNoActivityTimeout. It’s possible that this is not any issue
other than super slow network / proxy.

Will try higher timeout and observe for a while.

fix(ngRoute): remove unnecessary call to decodeURIComponent

Since `$location.$$path` is already decoded, doing an extra `decodeURIComponent` is both unnecessary
and can cause problems. Specifically, if the path originally includes an encoded `%` (aka `%25`),
then ngRoute will throw "URIError: URI malformed".

fix($rootScope): $watchCollection should handle NaN in objects

This fixes a potential infinite digest in $watchCollection when one of the values is NaN. This was previously fixed for arrays, but needs to be handled for objects as well.

Closes #7930
fix(select): force visual update in IE

IE9, IE10 and IE11 would always show the first <option> as
selected when the user moves from a null <option>
to a non-null one in a non-null <select>.
Even though the model was being updated correctly,
visually, the first <option> always appeared selected.

Setting the `selected` property twice in a row
seems to fix it in all the three versions mentioned above.

revert: feat(*): lazy one-time binding support

This reverts commit cee429f0aaebf32ef1c9aedd8447a48f163dd0a4.

See #7700 for a more performant approach for bind-once.
perf(*): more performant interpolation and lazy one-time binding

BEAKING CHANGE:
Lazy-binding now happens on the scope watcher level.

What this means is that given `parseFn = $parse('::foo')`,
bind-once will only kick in when `parseFn` is being watched by a scope
(i.e. `scope.$watch(parseFn)`)

Bind-once will have no effect when directily invoking `parseFn` (i.e. `parseFn()`)
