[css-anchor-position] Potentially moving the "Conditional Hiding: the position-visibility property" section

[jwatt]

Hiding due to the position-visibility property does not really relate more to Anchor-Based Positioning than to Anchor-Based Sizing. So it's unclear to me why the Conditional Hiding: the position-visibility property subsection logically belongs under the "Anchor-Based Positioning" section.

To my mind it would make more sense for the "Conditional Hiding" subsection to be a subsection at the end of the Overflow Management section.

My reason for suggesting putting it at the END of the Overflow Management section is because the description of the no-overflow value makes reference to the position-try property already discussed in that section.

If the box overflows its inset-modified containing block even after applying position-try, then the box is strongly hidden.
