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.

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.

This turns the embedded group into a pointer.
Note: Older files will not load the grease pencil v3 object properly after this.
The objects will not have any layers in them.

Code in charge of fixing invalid liboverride hierarchy roots would be
too agressive in re-assigning new root in replacement of old one. When
the invalid initial case was a 'low-level' type of ID (like a nodetree
e.g.), it could 'contaminate' many valid data (objects etc.) and force
them into its own local hierarchy.
This commit fixes the issue by storing all 'processed as valid' IDs into
a set, and ensuring that once an ID has been put into that set, its
hierarchy root is not changed anymore.
in other words, it changes the old behavior of 'last encountered hierarchy
wins' to 'first encountered hierarchy wins'. Since higher-level types of
IDs (like collections or objects) are processed first, this is the
most logical behavior too.
In some cases we store temporary region data that doesn't require
freeing. Code shouldn't expect the data pointer to be unset in this
case, so don't print an error.
Move the node previews to the overlay region, atop each node.
It allows nodes to keep the same size when the preview is toggled,
which is more convenient for large nodes and large nodetrees.
The preview has to be drawn from `node_draw_extra_info_panel`
because there could be overlapping between info text and the preview.
When the node is out of the view, it also has to make sure that the
preview is also out of the view before exiting the draw function.
