For the Module Template Layout to render FlashMessages, it
needs to hold the FlashMessageQueue with the added messages.
This needs to be done manually for extbase extensions, as
they are holding their own internal queue.

This patch also reverts the related patch #97569, which
fixed it by adding an explicit f:flashMessages VH to the
templates.
