Fix a plethora of style issues that lead to a worse touch experience.
I tried to optimize these solutions so that they didn't reduce the layout
density too much. More updates may have to be made in the future.
Fix some problems with the Pre-12 widget responsiveness backport, most
notably the wrong layout being chosen on more dense launcher grids.
Also change the default widget size from 2x2 to 3x2 so that it's more
readable.
Refactor styles again, this time trying to seperate the more
layout-specific attributes so that layouts become more re-usable.
This also updates the naming conventions of styles.
Post widget responsive behavior back to Android 11 and below. This is
not the nicest solution [mostly since the UI flickers when resizing],
but it seems to work well enough.
The plans for widgets have changed somewhat. Instead of 4 or so
variants, there will instead be one unified widget that chooses
different layouts depending on its size. The first one added is the
full widget, which shows more controls as long as theres enough
space.
