Reverting the previous fix to caption measurement, it caused a leak with
the listeners.

Changed implementations and APIs to use the non-deprecated Element class
wherever possible without breaking backwards compatibility.
* Methods defined in interfaces have not been touched.
* Return types have only been changed methods that should have no
existing third party callers (i.e. private, internal or @since 7.2)
* For methods that third party code might have overridden, the method
has been deprecated in favor of a new method that just delegates to the
old method.
* For methods that can't reasonably be overridden by third party code
(i.e. private, final, static, internal or @since 7.2), the parameter
type has been changed without retaining the old method.

This is the first step towards eliminating usage of the class. Reasoning
about upcoming steps will be easier when it's clear which class
"Element" refers to.

* Ensure e.g. expansion changes happen even if no hierarchy or
measurement changes (#10161)

sizes of children without expansion

measured
* Use measurements for fixing the height under more circumstances
* Only update based on hierarchy & state if something might have changed
