InkHUD refactoring (#6216)

* chore: todo.txt
* chore: comments
* fix: no fast refresh on VME290
Reverts a line of code which was accidentally committed
* refactor: god class
Divide the behavior from the old WindowManager class into several subclasses which each have a clear role.
* refactor: cppcheck medium warnings
Enough to pass github CI for now
* refactor: updateType selection
* refactor: don't use a setter for the shared AppletFonts
* fix: update prioritization
forceUpdate calls weren't being prioritized
* refactor: remove unhelpful logging
getTimeString is used for parsing our own time, but also the timestamps of messages. The "one time only" log printing will likely fire in unhelpful situations.
* fix: " "
* refactor: get rid of types.h file for enums
* Keep that sneaky todo file out of commits
