Previously the panel type name of a modifier (e.g. "MOD_PT_Smooth") was
created by copying from the ModifierTypeInfos name.
This meant that modifiers with the same default name would use
the same identifier for the panels.
Since different object types (e.g. OB_GREASE_PENCIL and OB_MESH)
might want to use the same default modifier name, this PR introduces
an idname field in the ModifierTypeInfo struct. This is then used to
generate the panel type name.
For compatibility reasons, the idname is the same as the name for now.
Note: Because the name was used previously, this means that some
modifiers have spaces in their panel type name.
E.g. "MOD_PT_Volume to Mesh".

Currently, while calculating face corner normals, Blender retrieves
custom normal data with write access. When the the custom normals in a
single smooth corner fan don't match, they are reset to the average
value.
This behavior is very old, but it comes from when Blender didn't have a
strong idea of const correctness. Indeed, modifying custom normal data
while calculating normals isn't threadsafe, which is important because
normals are calculated for viewport drawing, for example. And in the
future, properly caching face corner normals (see #93551) will require
the ability to calculate normals on a properly const mesh.
The fix is to still use the average of custom normals in a fan, but
not write that back to the custom data array. In my testing the results
are the same. Setting custom normals still fills the same value for all
corners in a fan.

This is mostly boilerplate code to add a new `GeometryComponent` as well as making sure
the new `GeometryComponent::Type` is handled in all the `switch` statements.

Take into account the filtering flags while filtering grease pencil channels in the grease pencil dopesheet.
This PR also adds two API functions for layers :
* `is_empty` checks if a layer contains no frame, and
* `is_selected` checks if a layer is selected.

Implements the rest of #101689, after 5e9ea9243b.
- `vdata` -> `vert_data`
- `edata` -> `edge_data`
- `pdata` -> `face_data`
- `ldata` -> `loop_data`
A deeper rename of `loop` to `corner` will be proposed as a next
step, and renaming `totvert` and `totedge` can be done separately.

The current face index can always be retrieved from the "loop_to_face"
map, so passing it around and updating it manually just adds more
state to track.
Utility functions make accessing the next and previous corner of a face
more obvious, and range based for loops make iterating over corners
or vertices in a face simpler too.
Implements part of #101689.
The "poly" name was chosen to distinguish the `MLoop` + `MPoly`
combination from the `MFace` struct it replaced. Those two structures
persisted together for a long time, but nowadays `MPoly` is gone, and
`MFace` is only used in some legacy code like the particle system.
To avoid unnecessarily using a different term, increase consistency
with the UI and with BMesh, and generally make code a bit easier to
read, this commit replaces the `poly` term with `poly`. Most variables
that use the term are renamed too. `Mesh.totface` and `Mesh.fdata` now
have a `_legacy` suffix to reduce confusion. In a next step, `pdata`
can be renamed to `face_data` as well.

Even if a text datablock was "used" by in the Text Editor, it would be
lost after save/reload if no fake user is set.
This is not in line with other datablocks if they are used by an editor
(e.g. images, clips, masks etc.).
Now handle this with `IDWALK_CB_USER_ONE` (instead of `IDWALK_CB_NOP`)
in `id_refcount_recompute_callback` >
`BKE_screen_foreach_id_screen_area` which re-ensures a user is set.
(Bit on shaky ground here, but this seems like this is how this is
handled for other editors "consuming" a datablock).

Clipping should use `clipr`instead of `curr`.
`clipr` is for value clipping while `curr` is for curve view clipping,
misuse of these two can lead to output value being clipped by
viewing range. Now fixed.

Adds the UI for layer opacity in the layer panel.
Currently layer blending rendering is not implemented, so the last layer's opacity will affect all of the layers.

This change replaces a bare RenderEngine owned by a viewport
with a VeiwRender. This unlocks a possibility of accessing
RenderResult for viewport renders. Currently it is not done,
but it will be needed for an upcoming work towards unification
of the render passes handling.

It is possible to organize shape keys into a tree through the
reference key setting. Mesh editing and sculpting a reference
key is supposed to update all its children, but this was only
done for one level of dependencies.
This changes the code to retrieve the complete set of dependent
keys and update them all.
In order to better suit the upcoming changes of shader node previews, this
patch replaces the old implementation of the storage of the compositor
previews. It also prevents memory loss for future modification.
BKE_node_preview_clear_tree was removed as it is no longer needed and
will not be used by the new shader node previews.

Also see #103343.
Couldn't move two files yet:
* `softbody.c`: The corresponding regression test fails. It seems like the
conversion to C++ changes floating point accuracy, but it's not clear where that happens exactly.
* `writeffmpeg.c`: Is a bit more complex to convert because of the static array in `av_err2str`.

CustomData_bmesh_copy_data_exclude_by_type was excessively optimized.
It only worked if the ordering (by name) of the attributes in both
customdata sets were the same.
Note that a blender::Set is used (with 32 slots of static storage)
to keep track of uninitialized destination layers.
Alternatives include:
* Storing a bitflag in CustomDataLayer.flag
* Using a static bool vector instead.
I don't especially care how it's done, pick one.
