This is in the interests of allowing the frontend team to experiment with
switching from XUL grid to CSS grid, without inadvertently changing the
display values for the grid items via css-grid-item blockification.
This patch's new pref is not expected to remain in the codebase for long.
We're just adding it so that the behavior remains the same by default, because
we do currently have some XUL code that inadvertently depends on -moz-box
display values being blockified to 'block'. The plan is for folks to remove
that dependency e.g. by adding explicit 'display:block' styling to frontend
code as-needed. After we've done that, we can tentatively flip the pref to true
by default, and then remove the pref entirely.

Currently, there's no way to tell whether the SIDEWAYS bit is set from
`writing-mode:sideways-*` or `writing-mode:vertical-*; text-orientation:sideways;`.
To be able to tell them apart, split SIDEWAYS bits into VERTICAL_SIDEWAYS
and TEXT_SIDEWAYS. This is needed by my proposed solution in bug 1102175.
Also, provide convenience methods related to sideways writing-mode, and replace
obscure checks in the codebase.
Note that we don't have the use cases to distinguish vertical-rl from
sideways-rl in layout, but for the completeness, IsSidewaysLR() is still
defined.

In particular: in our frontend code, if we happen to end up with a flex/grid
item with 'display:-moz-box', we want it to take the same sizing codepath as
other flex/grid items, which are all block-level (even though -moz-box is not
exactly block-level itself). Notably, we want to use ComputeSizeFlags::eDefault
for sizing (like we do for real block-level things), because that's necessary
in order for grid items to stretch correctly in their inline axis.
Also: this patch renames "isBlock" to "isBlockLevel" to reflect reality. Its
naming is based on the constant NS_CSS_FRAME_TYPE_BLOCK, which in fact is not
specific to 'display:block' but in fact is for frames that are "block-level in
normal flow" (which I think in practice means block-level and not
out-of-flow). That is documented here:

Now that we count them, I think we should do this.
This property is pretty painful for various reasons:
* It's a pretty awkward non-standard property.
* Has a pretty short name, so people use it instead of the standard
alternatives.
* We cannot really even implement it easily anyhow, without breaking a whole
bunch of stuff, because pages do things like:
```
myelement {
zoom: 0.5;
-moz-transform: scale(0.5);
transform-origin: 0 0;
}
```
For now this is only recorded when CSS use counters are enabled (Nightly for
now), but I want to change it once bug 1578661 is in central.
The hope is that this warning slightly raises awareness of this property not
being standard. You get a CSS parsing error in the console, but those are
usually too noisy and disabled by default.

This partially addresses the regression, but not fully. With this patch we don't
maintain shadow trees for nodes that we know won't get rendered.
This works fast in WebKit / Blink because of a bug in their implementation which
doesn't synchronize style attributes, introduced in [1].
You can see this clearly if you click on the bug's test-case and inspect the
<use> shadow trees (there's no style="stroke:orange" whatsoever).
They can kinda get away with it because they don't properly implement SVG 2. In
particular, in Blink / WebKit, the style of the element in the <use> shadow tree
is the style of the referenced element, which means that even if the style
attribute isn't properly synced it's ~ok since it doesn't end up mattering for
styling.
Easiest test-case for the behavior difference is:
```
<!doctype html>
<style>
rect:hover {
fill: green;
}
</style>
<svg width=300 height=300>
<g id="canvas">
<rect fill=red width=100 height=100></rect>
</g>
<g>
<use x=200 href="#canvas"></use>
</g>
</svg>
```
Where Firefox will properly update each square independently when hovered, but
Blink / WebKit won't.
This used to work faster because in this particular test-case we have 3 hidden
<use> elements whose href is the #canvas, which is basically everything.
Before moving to shadow trees we'd do it using anonymous content, and since we
never got a frame we'd never clone the subtree in the first case.
This case was faster before bug 1450250, but this approach makes other cases
slow that were fixed by that bug, like bug 1485402.
So I'll try to optimize shadow tree syncing instead, I guess, but there's no
good reason not to land this in the meantime IMHO.

This is much easier than the existing ResizeReflowIgnoreOverride function, and
this will allow me to avoid flushing if needed (we already kinda do that
already with the "suppressResizeReflow" thing), which in turn allows me to
consolidate a bunch of the logic for resizes.
The function should be much easier to follow:
* Set the new viewport (async, doesn't do any work).
* Invalidate layout as needed due to the viewport change (that is, resize hint
for the root frame, and invalidate isizes if needed). Also async and doesn't
do any reflowing itself.
* Flush layout / do the reflowing all at once. I think we can stop doing this
much more often now, but that's follow-up work.

Per the css-contain specification, size contained element must be sized as if

the UA stylesheet (forms.css). This causes reftest that check that
size-contained <select> elements and empty ones look the same.
This commit fixes this by also shortcircuiting the (inline) size calculations
and returning 0 for empty <select> elements.
Replacing the by a zero width space would not have been enough, since
padding would still be added. It would have been possible to add it in the
inline size calculations of size-contained <select> elements as well, but this
padding serves not purpose when the element is empty, so removing it from there
has no downside, and shortcircuitig both cases is simpler (and marginally
faster) than adding the padding in both cases.
