When a transformed absolute containing block fragments across multi-column,
abspos children could paint in the wrong column. This happened because the
abspos display item was built when its placeholder was encountered during
display list traversal, and the placeholder could end up in a different column
than where the abspos should paint.
Extend `DisplayPushedAbsoluteFrames` (now renamed to
`DisplayAbsoluteFramesNotBuiltByPlaceholder`) to also directly build abspos
frames whose placeholder lived in a different continuation subtree. Skip
building those abspos frames when they are later traversed via their
placeholders.

I looked at this because in bug 2014331 I need to mark more pseudos as
element-backed, and it's kinda silly the state our setup is in right
now.
This is all a somewhat historical mess, because in the old style system
pseudo-elements were just atoms, and we had that different types of atom
setup. The source of truth for these right now lives in a header macro
file, which isn't very flexible.
But now we have PseudoStyleType which represents both pseudos and anon
boxes, and is similar to the rust side PseudoElement enum.
Plus, the ::-moz-tree pseudo-elements are defined as anon boxes which
doesn't make any sense, so move them to pseudo-elements while at it.
Unify this in a similar way we treat CSS properties: Source of truth is
in pseudo_elements.toml / anon_boxes.toml, and we generate Rust and C++
as needed. This allows removing the nsStaticAtom subclass thing from
XPCOM, too.
This avoids some nasty duplication around which pseudos are pref-gated
and what not as well.

It is replaced by a standard-conforming cast to (void) which is
understood the same by the compiler.
In some cases this could be replaced by `[[maybe_unused]]` but for
expression whose value is ignored, this requires storing to a temporary
variable first, so not going that way.
One notable change is that marking an object of type already_AddRefed as
unused used to implicitly leak memory. This is now made explicit.

No behavior change, but this saves some per-child work and conceptually
is the right thing to do. HidesContent() is non-trivial.
Add an assertion to make sure we don't enter BuildDisplayListForChild
at all if content is hidden.
I audited all the callers, and the ones I didn't touch can't have

This patch changes the signature to `GetMinISize()`, `GetPrefISize()`,
`IntrinsicISize` by adding a helper struct as a preparation. Then we can just
add more data such as a percentage basis to the struct without altering the
signature in the future.
When passing `IntrinsicSizeInput` struct down to another helper method, we
generally just pass the original one if the method is computing the intrinsic
size of our own or our anonymous children. If the method is computing our
children's intrinsic contribution, we'll need to create a brand new
`IntrinsicSizeInput` for our children.

Most frame types have identical or very similar implementation for GetMinISize()
and GetPrefISize(), and many of them already have `IntrinsicISize()` to unify
the implementation. This patch introduces nsIFrame::IntrinsicISize() so that
derived classes only need to override one method.
`nsBlockFrame`, `ColumnSetWrapperFrame`, and `nsColumnSetFrame` are the only
three classes where their `GetMinISize()` and `GetPrefISize()` have significant
differences. Therefore, we rename `GetMinISize()` and `GetPrefISize()` to
`MinISize()` and `PrefISize`, respectively, and use them as helpers to implement
their `IntrinsicISize()`.
This patch doesn't change behavior.

These frames have very similar implementations in `GetMinISize()` and
`GetPrefISize()`. Therefore, add helpers to avoid code duplication. The helpers
are named `IntrinsicISize()` to match existing helpers in flex & grid container.
Drop "Get" in `GetIntrinsicISize()` for `nsFieldSetFrame` and
`nsComboboxControlFrame` to match our coding style because it always returns a
value.

After D198523, NS_BLOCK_FLOAT_MGR and NS_BLOCK_MARGIN_ROOT are always
set simultaneously when initiating a frame, so we can merge them into a
single NS_BLOCK_STATIC_BFC flag. The freed bit is used to define a new
NS_BLOCK_DYNAMIC_BFC flag that has the same effect and is now used for
frames with paint/layout containment so that in D197043 they can be
updated later without having to reconstruct the frame tree. Finally
NS_BLOCK_BFC_STATE_BITS is the bitwise union of these BFC flags.
The following changes are made and cause no behavior changes:
- Instead of testing whether NS_BLOCK_FLOAT_MGR or NS_BLOCK_MARGIN_ROOT
is set, or whether all of the bits from
NS_BLOCK_FORMATTING_CONTEXT_STATE_BITS are set, we test whether any
of the NS_BLOCK_BFC_STATE_BITS is set.
- Instead of adding NS_BLOCK_FORMATTING_CONTEXT_STATE_BITS when
constructing a frame, we add NS_BLOCK_STATIC_BFC. The exception is
for frame with paint/layout containment, for which we set
NS_BLOCK_DYNAMIC_BFC instead.
