ReaderZooming: Deal with some more fallout of the new zoom modes (#7728)
* Namely, ensure zoom_mode is consistent with genus & type *both ways*. (I only dealt with the "no zoom_mode" case in my original fixup).
Because documents with settings dating back from before the new zoom modes had "old" zoom_mode settings mixed with "new" genus/type defaults that didn't agree with each other.
It lead to super-confusing ConfigDialog behavior, because ConfigDialog was in fact not reflecting the reality.
(As the source of truth is actually `zoom_mode`).
* There was a snafu in manual mode, because of the extremely weird way prefixes are handled by Configurable/ReaderConfig/DocSettings/ConfigDialog.
So, make sure we only have a *single* zoom_factor, and that it's updated and saved properly under the right name everywhere.
Fixes inconsistencies between first swapping to manual mode, and what the ConfigDialog said/did (because again: possibly a lie), vs., re-opening the same document, which would magically use *different* settings, closer to what was expected (but still broken because of the prefix mismatch and a disagreement on defaults between the two variants).

Enable HW dithering in a few key places (#4541)
* Enable HW dithering on supported devices (Clara HD, Forma; Oasis 2, PW4)
* FileManager and co. (where appropriate, i.e., when covers are shown)
* Book Status
* Reader, where appropriate:
* CRe: on pages whith image content (for over 7.5% of the screen area, should hopefully leave stuff like bullet points or small scene breaks alone).
* Other engines: on user-request (in the gear tab of the bottom menu), via the new "Dithering" knob (will only appear on supported devices).
* ScreenSaver
* ImageViewer
* Minimize repaints when flash_ui is enabled (by, almost everywhere, only repainting the flashing element, and not the toplevel window which hosts it).
(The first pass of this involved fixing a few Button instances whose show_parent was wrong, in particular, chevrons in the FM & TopMenu).
* Hunted down a few redundant repaints (unneeded setDirty("all") calls),
either by switching the widget to nil when only a refresh was needed, and not a repaint,
or by passing the appropritate widget to setDirty.
(Note to self: Enable *verbose* debugging to catch broken setDirty calls via its post guard).
There were also a few instances of 'em right behind a widget close.
* Don't repaint the underlying widget when initially showing TopMenu & ConfigDialog.
We unfortunately do need to do it when switching tabs, because of their variable heights.
* On Kobo, disabled the extra and completely useless full refresh before suspend/reboot/poweroff, as well as on resume. No more double refreshes!
* Fix another debug guard in Kobo sysfs_light
* Switch ImageWidget & ImageViewer mostly to "ui" updates, which will be better suited to image content pretty much everywhere, REAGL or not.
