This introduces a context path to the spreadsheet editor, which contains
information about what data is shown in the spreadsheet. The context
path (breadcrumbs) can reference a specific node in a node group
hierarchy. During object evaluation, the geometry nodes modifier checks
what data is currently requested by visible spreadsheets and stores
the corresponding geometry sets separately for later access.
The context path can be updated by the user explicitely, by clicking
on the new icon in the header of nodes. Under some circumstances,
the context path is updated automatically based on Blender's context.
This patch also consolidates the "Node" and "Final" object evaluation
mode to just "Evaluated". Based on the current context path, either
the final geometry set of an object will be displayed, or the data at
a specific node.
The new preview icon in geometry nodes now behaves more like
a toggle. It can be clicked again to clear the context path in an
open spreadsheet editor.
Previously, only an object could be pinned in the spreadsheet editor.
Now it is possible to pin the entire context path. That allows two
different spreadsheets to display geometry data from two different
nodes.
The breadcrumbs in the spreadsheet header can be collapsed by
clicking on the arrow icons. It's not ideal but works well for now.
This might be changed again, if we get a data set region on the left.

This also fixes the issue that the width of the "Name" column
when viewing instances does not resize correctly.

A `DataSource` provides columns for the spreadsheet to display.
Every column has a SpreadsheetColumnID as identifier. Columns
are not generated eagerly anymore, instead the main spreadsheet
code can request a column from a data source with an column
identifier. The column identifiers can be stored in DNA and allow us
to store persistent data per column.
On the user level the only thing that changes is that columns are
not shown in alphabetical order anymore. Instead, new columns
are always added on the left. The behavior can be changed,
however I'd prefer not to automate this too much currently. I think
we should just add operators to hide/reorder/resize columns soonish.

Previously, the spreadsheet editor could only show data of the original
and of the final evaluated object. Now it is possible to show the data
at some intermediate stages too.
For that the mode has to be set to "Node" in the spreadsheet editor.
Furthermore, the preview of a specific node has to be activated by
clicking the new icon in the header of geometry nodes.
The exact ui of this feature might be refined in upcoming commits.
It is already very useful for debugging node groups in it's current
state though.

This patch renames two domains:
* `Polygon` -> `Face`
* `Corner` -> `Face Corner`
For the change from `polygon` to `face` I did a "deep rename" where I updated
all (most?) cases where we refere to the attribute domain in code as well.
The change from `corner` to `face corner` is only a ui change. I did not see
a real need to update all code the code for that. It does not seem to improve
the code, more on the contrary.

We cannot use `std::variant` yet, because not all of the compilers
we support have a working version of it yet. For now, I just replaced
it with multiple `std::option` which is good enough, because currently
`CellValue` is only used for the cells that are actually drawn in
the spreadsheet.
This patch adds data about instances generated by geometry nodes
to the spreadsheet. The transform data is decomposed into position,
rotation, and scale, and there is a name column to display the name
of the instanced object or collection.
This data is implemented specifically for the spreadsheet, because
we're not sure that we want to expose this data as attributes for the
use elsewhere.
Differential Revision: https://developer.blender.org/D10770
This is a refactor and no functional changes are expected.
The goal is to make it simpler to add other data sources without having
to repeat the drawing code everywhere. Also, having the `CellValue` class
allows us to implement filtering and sorting in a more generic way.
There are two caveats of the current implementation which still need
to be resolved in a separate step:
* In theory the data on the original object can be editable in the spreadsheet.
* If a complex object is in edit mode, and its original data is displayed,
the drawing code can be slow, because the bmesh is converted to a mesh
every time. The proper solution is to draw the data from the bmesh directly.
This should become easier after an upcoming refactor.

This implements the status bar as footer region in the
spreadsheet editor.
It shows the total number of rows and columns as well
as how many rows are actually visible (based on the filter).
The implementation stores the stats in a runtime struct during
drawing and the status bar reads from that struct.

This implements the MVP for the new spreadsheet editor (T85879). The functionality
is still very limited, but it proved to be useful already. A more complete picture
of where we want to go with the new editor can be found in T86279.
Supported features:
* Show point attributes of evaluated meshes (no original data, no other domains,
no other geometry types, yet). Since only meshes are supported right now, the
output of the Point Distribute is not shown, because it is a point cloud.
* Only show data for selected vertices when the mesh is in edit mode.
Different parts of Blender keep track of selection state and original-indices with
varying degrees of success. Therefore, when the selected-only filter is used, the
result might be a bit confusing when using some modifiers or nodes. This will
be improved in the future.
* All data is readonly. Since only evaluated data is displayed currently, it has to
be readonly. However, this is not an inherent limitation of the spreadsheet editor.
In the future editable data will be displayed as well.
Some boilerplate code for the new editor has been committed before in
rB9cb5f0a2282a7a84f7f8636b43a32bdc04b51cd5.
It would be good to let the spreadsheet editor mature for a couple of weeks as part
of the geometry nodes project. Then other modules are invited to show their own data
in the new editor!

This adds the initial boilerplate code that is required to introduce
the new spreadsheet editor. The editor is still hidden from the ui.
It can be made visible by undoing the change in `rna_screen.c`.
This patch does not contain any business logic for the spreadsheet editor.
