Subject: feat(filter): allow map of filters to be registered

This feature adds similar functionality to what `$ControllerProvider.register`
and `$CompileProvider.directive` currently provide by allowing a map of filter
name/factories to be passed as the sole argument to `$FilterProvider.register`
to register all of the specified filters.

Closes #4036
Closes #4091
