This is a pretty quick fix; the solution is just removing all the
instanced panels whena panel is unregistered. This also necessitates
adding the option to call UI_panels_free_instanced with NULL context.

This implements a general system to implement drag and drop, subpanels,
and UI animation for the stack UIs in Blender. There are NO functional
changes in this patch, but it makes it relatively trivial to implement
these features for stacks.
The biggest complication to using panels to implement the UI for lists
is that there can be multiple modifiers of the same type. Currently there
is an assumed 1 to 1 relationship between every panel and its type, but
there can be multiple list items of the same type, so we have to break
this relationship. The mapping between panels and their data is stored
with an index in the panel's runtime struct.
To make use the system for a list like modifiers, four components
must be added:
1. A panel type defined and registered for each list data type, with a
known mapping between list data types and panel idnames.
1. A function called by interface code to build the add the panel
layouts with the provided helper functions.
- UI_panel_list_matches_data will check if the panel list needs to
be rebuilt.
- UI_panels_free_instanced will remove the existing list panels
- UI_panel_add_instanced adds a list panel of a given type.
3. An expand flag for the list data and implementations of
get_list_data_expand_flag and set_list_data_expand_flag.
4. For reordering, the panel type's reorder callback. This is called
when the instanced panels are drag-dropped. This requires
implementing a "move to index" operator for the list data.

Note this only changes cases where the variable was declared inside
the for loop. To handle it outside as well is a different challenge.

Follow up of b2ee1770d4 and 10c2254d41, part of T74432.
Now the area and region naming conventions should be less confusing.
Mostly a careful batch rename but had to do few smaller fixes.
Also ran clang-format on affected files.
Note, the performance of the tests we run here is still bad since we have plenty
of panels around. But better than the crash.

This fixes poor Cycles panel ordering, with Freestyle and Custom Properties
appearing at the top.
For most cases order of registration is still the easiest way to control
order and it's recommended to keep using that. This is mainly to solve a few
cases where we want a few built-in panels to appear below add-on panels.
Use this for the save confirmation dialog so it has a default action
when pressing enter which draws with a highlight so it's clear what the
default action is (the dialog was just closing before).

BF-admins agree to remove header information that isn't useful,

This is often invalid, outdated or misleading
especially when splitting files.
It's more useful to git-blame to find out who has developed the code.

Too many things done wrong in original rBd12b3767f81d to list them all
here, hopefully nothing bad sneaked in again this time :|
Also cleaned up a little the 'sort by name', even though (since we only
have two options by default, sort by index and by name) we can abuse it
as a binary option for now, this is not a bitflag...
Now, it was possible to invert the order of the UIlist using the filter, but it was impossible to know if the list was inverted or not.
The problem with this is that any other element depending of this value could not be adjusted.
See https://devtalk.blender.org/t/how-to-access-uilist-properties/2268
The new parameter allows to set the reverse order by default. When the list is set as reverse, it cannot be inverted again, so the invert button is removed of the filter.
This change is needed to fix a requested feature for Grease Pencil (T56985) and because a lot of 2D softwares use the drawing layers in the inverse order used in Blender.
