Since we want to start collecting all form data through mapFrameTree on Fennec,
too, we need to change our filtering strategy for form data.
We can no longer bail out directly during the data collection loop and instead
have to filter the data after having collected all of it.
The easiest way to do that is to start using PrivacyFilter.filterFormData() on
Android as well.

GeckoView has already started using a slightly modified version of mapFrameTree,
and since ssu.forEachNonDynamicChildFrame() has vastly simplified the process of
correctly using FormData/ScrollPosition.collect() for *all* (non-dynamic) child
frames, we want to use mapFrameTree for Fennec's session store as well.
Therefore, to avoid further duplication of code, we add a common version to the
session store's Utils.jsm module.
We base the code on the GeckoView implementation of mapFrameTree, which has
gained the ability to use callback *arrays*, however we still use ssu.forEach-
NonDynamicChildFrame() like Desktop currently does, instead of simply iterating
over *all* frames.

This is used in JS via instanceof checks, and in C++ only to get the `inputField`
attribute (the actual HTML input or textarea). We can swap out instanceof by checking
the tag name, and we can directly query for the input field from C++.

This patch was autogenerated by my decomponents.py
It covers almost every file with the extension js, jsm, html, py,
xhtml, or xul.
It removes blank lines after removed lines, when the removed lines are
preceded by either blank lines or the start of a new block. The "start
of a new block" is defined fairly hackily: either the line starts with
//, ends with */, ends with {, <
