layout: Make transform-style: preserve-3d establish a containing block for all descendants (#35808) 
* layout: Fix behavior of `transform-style: preserve-3d`

This makes `transform-style: preserve-3d` establish a containing block
for all descendants, as specified here:
<https://drafts.csswg.org/css-transforms-2/#transform-style-property>

* layout: Check for transformable elements

Adds a new `is_transformable` helper method and use this in several other
methods, including the methods for whether the fragment establishes a
new stacking context or a containing block for all descendants.

* layout: Fix stacking context & containing block checks.

Only the computed value of `transform-style` should be used to determine
whether the element establishes a stacking context and/or a containing
block, not the used value.

* Update clip-no-stacking-context test expectation to pass.
