[PATCH v4 3/9] vidconsole: Add damage notifications to all vidconsole drivers

[Alexander Graf <agraf@csgraf.de>]

Now that we have a damage tracking API, let's populate damage done by
vidconsole drivers. We try to declare as little memory as damaged as
possible, with the exception of rotated screens that I couldn't get my
head wrapped around. On those, we revert to the old behavior and mark
the full screen as damaged on every update.

v1 -> v2:

  - Fix ranges in truetype target
  - Limit rotate to necessary damange
