While looking at the backout, I noticed table parts relied on reframing
on abspos-container-ness changes in a subtle way, see the test, which
fails with the first patch of this bug applied without these changes.
Make the NS_FRAME_CAN_HAVE_ABSPOS_CHILDREN mean the same for table parts
as for everything else. Instead, keep the registration status on each
relevant frame class individually.
Depends on D169127

Teach nsDisplay{Filters,BackdropFilters} to use a style that doesn't
belong to mFrame for the root frame, and use it as needed.
Remove the BackdropFilters::CanCreateWebrenderCommands call because it
was testing for StyleSVGEffects::mFilters rather than mBackdropFilters,
so it was doing nothing.

`nsIFrame::IsRelativelyPositioned()` tests "position:relative" or
"position:sticky", but its naming is misleading until you've dug into the
underlying helper `nsStyleDisplay::IsRelativelyPositionedStyle()`.

Make sure it's always in sync with the style.
Keeping a boolean field was useful when we didn't handle dynamic changes
to it, but now we do it's just redundant, and could cause correctness
issues.

But in this case the transform property wouldn't apply to the element so
there's no reason to create a stacking-context.

Also: adjust include paths to be consistent for usages of various SVG headers,
and remove unused SVG includes (mostly for "utils" classes),
and drop stray "ns" from already-renamed SVG classes in various code comments.

The trickier part is that we represent -moz-image-rect as a Rect() type instead
of image with non-null clip-rect. So we need to add a bit of code to
distinguish "image request types" from other types of images.
But it's not too annoying, and we need to do the same for fancier images like
image-set and such whenever we implement it, so seems nice to get rid of
most explicit usages of nsStyleImage::GetType().

Storing it in the style value doesn't make much sense, specially since we store
drawing-dependent stuff there like the svg viewport size, which clearly depends
on the size of the frame.
This cache may not be very useful anymore, see the linked bug, but this unblocks
me with other style system cleanups and seems safer.

This fixes the regression of three web-platform-test reftests:
testing/web-platform/tests/css/css-contain/contain-paint-002.html
testing/web-platform/tests/css/css-contain/contain-paint-011.html
testing/web-platform/tests/css/css-contain/contain-paint-012.html
that was caused by patch 1, but it's written on top of the code in
patches 2 and 3 so it's easier to fix afterwards.

This fixes a rather subtle bug. What the underlying code here is trying
to do is remove nsChangeHint_UpdateContainingBlock when some properties
that influence whether a frame is a containing block for absolutely
positioned or fixed positioned elements have changed, but the final
calculation of being a containing block has not changed. However, the
old code was using a function that tested whether the style could
*possibly* lead to a frame being a containing block. Some of the
properties (like the transform properties) that lead to being a
containing block, for example, don't apply to non-replaced inlines.
Some, however, do (such as 'filter'). So if there's a dynamic change
adding or removing a filter, on an inline that also has an *ignored*
transform property (like 'transform' or 'perspective') set, then the
code prior to this patch causes us to remove the UpdateContainingBlock
hint.
This patch fixes things by testing whether being a containing block
could have changed for *any* type of frame, by separately testing the
changes.
The added tests fail without the patch and pass with the patch, viewed
in isolation. However, without the previous patch, test 003 passes.
Test 003 also fails in Chrome (but 001 and 002 pass).

This patch basically does:
* remove StyleSetHandle and its corresponding files
* revisit #includes of related header files and change correspondingly
* change nsIPresShell::mStyleSet to be UniquePtr<ServoStyleSet>
* change the creating path of ServoStyleSet to pass UniquePtr
* change other mentions of StyleSetHandle to ServoStyleSet*
* remove AsServo() calls on ServoStyleSet
Some unfortunate bits:
* some methods of (Servo)StyleSet only accepts ServoStyleSheet while
many places call into the methods with StyleSheet, so there are many
->AsServo() added to sheets
