android, desktop: mirror more RTL icons and placements

Add Painter.mirrorIfRtl() for icons drawn by shared helpers that take a
Painter, and use it for the delivery receipts "Don't enable" chevron and
the "Show message status" arrow. Mirror the forwarded delivery status
chevron. Place the rows of framed messages (e.g. image captions), the
group member name row and the supporter banner image relative to the
layout direction.

Update the plan: these are no longer deferred, and correct its
descriptions of the dropdown, the chat list header and the tail side.
