This commit adds a new `customFilter()` function on `$animateProvider` (similar to `classNameFilter()`), which can be used to filter animations (i.e. decide whether they are allowed or not), based on the return value of a custom filter function. This allows to easily create arbitrarily complex rules for filtering animations, such as allowing specific events only, or enabling animations on specific subtrees of the DOM, etc. Fixes #14891
