Geometry Nodes: Expose texture and material inputs to modifier

This allows choosing material and texture sockets for the group input
node in the modifier. Note that currently grease pencil materials are
displayed in the list, even though grease pencil data is not supported
yet by geometry nodes. That is more complicated to fix in this case,
since we use IDProperties to store the dynamic exposed inputs.

Cleanup: Fix forward declaring class with "struct"

Fix build error: Make CurveEval a struct

We need a pointer to this in DNA, which means it cannot be a class.

Cleanup: rename blender-launcher source file.

blender-laucher.c was not an ideal name for this file
since it's not directly clear it is windows only.

This change renames it to blender_launcher_win32.c
to be more in line with other win32 specific files
we have.

Geometry Nodes: Draw curve data in the viewport

This patch adds relatively small changes to the curve draw
cache implementation in order to draw the curve data in the
viewport. The dependency graph iterator is also modified
so that it iterates over the curve geometry component, which
is presented to users as `Curve` data with a pointer to the
`CurveEval`

The idea with the spline data type in geometry nodes is that
curve data itself is only the control points, and any evaluated
data with faces is a mesh. That is mostly expected elsewhere in
Blender anyway. This means it's only necessary to implement
wire edge drawing of `CurveEval` data.

Adding a `CurveEval` pointer to `Curve` is in line with changes
I'd like to make in the future like using `CurveEval` in more places
such as edit mode.

An alternate solution involves converting the curve wire data
to a mesh, however, that requires copying all of the data, and
since avoiding it is rather simple and is in-line with future plans
anyway, I think doing it this way is better.

Fix T88452: Point Separate crash on curve component

The point separate node should create a point cloud from control points
in this case, but for now disable the node on curves to avoid the crash.

Cleanup: Use consistent variable names

Cleanup: rename BKE_main_id_{clear_newpoins => newptr_and_tag_clear}

It wasn't obvious this function cleared the tag as well.

Cleanup: remove duplicate LIB_TAG_NEW untag code

This patch removes unnecessary calls to `BKE_main_id_tag_all` where the
same job is done by `BKE_main_id_clear_newpoins` on the following line.

LibOverride: Add heuristic protection against infinite loop due to libraries inter-dependencies.

This is not supposed to happen, but better be safe than sorry, and
assume it is beyond unlikely that someone would use chains of over 10k

Refactor: Rename pass accessor in viewport parameters

No need to state that it is a viewport display pass, since the method
is within viewport parameters it is implied that parameters do belong
to the viewport.

Brings this code closer to the Cycles-X branch.

Refactor: Remove friend class from Cycles viewport parameters

Such pattern should only be used when it is really needed. Otherwise
just stick to a more regular design, without worrying who is the user
of the class. Otherwise it will be annoying to subclass or unit test.

Cleanup: const qualifier of return type

Cleanup: Use logical OR in Cycles background shader

Refactor: Naming in Cycles viewport methods

Makes it more explicit they operate on shading/light.

Gives room to move more viewport related settings into this class and
cover with specific or generic modification checks.

Cleanup: Redundnat member init in Cycles viewport parameters

Refactor: Move display pass to Cycles viewport parameters

Allows to centralize storage and modification checks in a single place,
avoiding duplication in the synchronization code.

Ideally we would somehow be able to more granularly modify Cycles side
objects. Leaving this for a future decision, because it might be better
to implement it as a graph on the sync side.

Cleanup: Unused include in Cycles
