The idea is to be able to call the right function during style resolution time
without doing a linear walk via nsCSSAnonBoxes::IsNonInheritingAnonBox.

I'm a bit concerned about the additional, probably un-inlineable, function call
in this path. I'm not sure how hot this path would be.

This patch removes support for mozapp iframes, leaving support for
mozbrowser iframes intact. Some of the code has been rewritten in order
to phrase things in terms of mozbrowser only, as opposed to mozbrowser
or app. In some places, code that was only useful with apps has been
completely removed, so that the APIs consumed can also be removed. In
some places where the notion of appId was bleeding out of this API, now
we use NO_APP_ID. Other notions of appId which were restricted to this
API have been removed.

The new name makes the sense of the condition much clearer. E.g. compare:
NS_WARN_IF_FALSE(!rv.Failed());
with:
NS_WARNING_ASSERTION(!rv.Failed());
The new name also makes it clearer that it only has effect in debug builds,
because that's standard for assertions.

The standard placement new function is declared to not throw, which
means that, per spec, a null check on its result is required. There are
a number of places throughout layout/ where we know that we are passing
non-null pointers to placement new (and receiving them as a return
value), and we are therefore doing useless work performing these null
checks.
Therefore, we should be using an operator new overload that doesn't
require the null check. MFBT has just such an overload, so use that.

Just like CSSPseudoElementType, which uses a special type to represent the
maximum length. We can replace "CSSPseudoClassType::NotPseudo + 1" with
"CSSPseudoClassType::MAX", which means the maximum length.

In order to convert CSSPseudoElementType into its underlying type easier,
we define CSSPseudoElementTypeBase. However, keep using uint8_t directly for
forward declarations.
This is the key change in this patch series; it changes the object we
use for style data (currently nsIStyleRule) identity. It allows
removing some hacks we have to deal with that for StyleRule, and avoids
having to write similar hacks for nsCSSKeyframeRule and nsCSSPageRule
(which are broken without this).
I confirmed locally that it is this patch that fixes both of the todo_is
mochitests, by building and testing with the patch queue through patch
11, and again through patch 12.
