Feature: #88962 - Re-implement old PIDupinRootline TypoScript condition

See forge#88962

Description

The PIDupinRootline condition in TypoScript has been reimplemented within the Symfony expression language.

A new property tree.rootLineParentIds has been added to the tree object which is available in the Symfony expression language to provide checks for all parent page IDs of the current rootline.

Impact

When using the classic PIDupinRootline condition, you can easily switch to the condition with the new expression:

Old TypoScript condition syntax:

[PIDupinRootline = 30]
    page.10.value = I'm on any subpage of page with uid=30.
[END]

New TypoScript condition syntax:

[30 in tree.rootLineParentIds]
    page.10.value = I'm on any subpage of page with uid=30.
[end]
