Introduce 'page_of_comment' filter. 

This filter allows developers to modify the output of `get_page_of_comment()`.

As a side effect of this new filter, comment page numbers will always be
returned as integers. Previously, they would sometimes be returned as floats -
eg `float(2.0)` instead of `int(2)`.

Props laceous.
See #13939.
