The glyph pixel space in which we rasterized glyphs differed from how we
rendered the rasterized glyphs in the shader. They need to be in
agreement because the glyph subpixel offset selected during
rasterization depends on it. This patch should make the paths consistent
with each other.
Additionally, during animations, we now snap the reference frame
relative offset ignoring the impact of any animated transforms. This
helps with minimizing glyph wiggling during the transition.

Per the css-contain specification, size contained elements must be sized as if
they were empty. Up until now, we've been handling that by just using "0" as
the intrinsic size of some components, but that doesn't actually match the size
of a "true" empty select, which has some nonzero width from:
(a) the default inline-axis padding on the display frame (added in a rule for
the ::-moz-display-comboboxcontrol-frame pseudo, in forms.css).
(b) the width (inline-size) of the display frame's "placeholder" space
character, which has a small intrinsic width (but which really only exists
for *block-axis* sizing and alignment, when no option is selected from
the dropdown).
This patch addresses issue (a) by explicitly adding the display frame's
inline-axis padding to size-contained elements, and it addresses issue (b) by
changing to use a zero-width space character in empty select elements.
So: as of this patch, size-contained select elements are getting a little wider
(to address (a)), and empty select elements are also getting a little skinnier
(to address (b)), and they'll end up being the same width.
(I chose U+FEFF "zero-width non-breaking-space" since we were previously using
a non-breaking space character. I'm not sure if the non-breaking aspect matters,
but I figured I'd preserve that to be on the safe side.)

Per the css-contain specification, size contained element must be sized as if
they were empty. The code added to handle size containment shortciruits the
(inline) size calculations, and returns 0. However, an empty <select> element
is rendered as if it contained a and some padding gets added to it by
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.

After enabling column-span, ColumnSet becomes an anonymous child under
ColumnSetWrapperFrame. It doesn't need to handle border and padding,
containment, and non-auto block-size. ColumnSet's final block-size is
simply the union of ::-moz-column-content frames' rects.
However, we should extend ColumnSet's block-size to consume the
available block-size if the ColumnSetWrapper's block-size is constrained
so that the column rules are drawn to the block-end edge of the multicol
container.

If the embedding element uses `object-fit`, then that indicates it's precisely
positioning and/or sizing the embedded SVG document's viewport to fit inside
the embedding element's content area. So, when the internal SVG viewBox
changes, then the embedding element needs to redo that positioning/sizing. For
now, this specifically requires a reflow (and in particular, the nsViewManager
adjustments at the end of nsSubDocumentFrame::Reflow).

Note that this is an imperfect implementation, in that it doesn't exactly
match the sizing behavior of a truly empty `<select>` element. I've filed
followup bug 1562057 on that. However, the behavior that's implemented
here *does* successfully make us ignore a `<select>`'s contents for sizing
purposes, and it's much better than what we do currently (which is pretty
broken via inheriting a partial `contain:size` implementation from our
parent class, nsBlockFrame).
