This patch implements the list panel system D7490 for modifiers.
It also moves modifier drawing to a callback in ModifierTypeInfo
in line with the extensible architecture refactoring goal T75724.
This adds a PanelRegister callback and utilities for registering
panels and subpanels. It also adds the callbacks for expansion saving
and drag and drop reordering described in D7490.
These utilities, callbacks, and other common UI elements shared
between modifiers live in MOD_ui_common.c.
Because modifier buttons are now in panels, we can make use of
subpanels for organization. The UI layouts also use the single
column layout style consistently used elsewhere in Blender.
Additionally, the mode-setting buttons are aligned and ordered
consistently with the outliner.
However, the large number of UI changes in this patch may mean
that additional polishing is required in master.
Thanks to William Reynish (@billreynish) who did a fair amount of the
layout work and to Julian Eisel (@Severin) for consistent help.

Optimizations in rBcda15408582e8de5b405 do not guarantee anymore that
consecutive memchunks in two consecutive undo steps are actually about
the same data (and hence can share the same buffer when unchanged).
This buffer sharing can now happen without any particular order, so we
need to change the process when 'merging' two undo memfiles together.
Note that existing code was not logically correct either, even with
previous undo storage code, since it would blindly transfer ownership of
the buffer to the second memchunk, without checking whether the first
one was actually the owner of it or not (a same buffer can be shared by
matching memchunks in many consecutive memfiles/undo steps).
Design Task: T76372
This part of a larger refactoring towards a more extensible architecture
in Blender: T75724
The API is defined in `BLO_read_write.h`. It adds the small data structures
`BlendWriter`, `BlendDataReader`, `BlendLibReader` and `BlendExpander`.
Those contain context about the current read/write operation. Furthermore,
it adds many functions with the prefixes `BLO_write_*`, `BLO_read_*` and
`BLO_expand_*`.
Lib linking and expanding will probably be handled by the more generic libquery
system eventually. The corresponding parts of the API can be removed then.
Mix up with imapaint.paintcursor & imapaint.paint.paint_cursor
Remove imapaint.paintcursor since it wasn't used.
Also rename paint_cursor_start_explicit() to paint_cursor_start(),
removing the existing paint_cursor_start() since it took the paint
struct from the context, a value that's known by all callers.
Most of the time current (based on order) system works fine, but when you add
or rename (i.e. re-sort) some ID, every data/memchunk afterwards would be out
of sync and hence re-stored in memory (and reported as changed).
Now we are storing the ID's session_uuid in the memchunks, which allows to
actually always find the first memchunk for an already existing ID stored in
previous undo steps, and compare the right memory.
Note that current, based-on-order system is still used almost all of the time,
search in the new ghash is only performed for a few data-blocks (when needed at all).

This is a temporary solution for T77173 for the 2.83 release. D7203
provides a more long term solution for future releases.
This adds theme colors for the three report backgrounds, setting them
to the color used in 2.82. A separate commit in the addons repository
will follow for changes to the bundled themes.
