Add an experimental "small message radius" toggle (#25305)

Add an experimental "small message radius" toggle.

This toggle allows switching to the pre-4.3.0, smaller message bubble
radius after an app restart. The message bubble radius styles now have
to be referenced via the Ui::BubbleRadius* and Ui::MsgFileThumbRadius*
wrappers to use the appropriate value.
