Add a method to remove points from the new curves type, just like
the existing curve removal function. No functional changes are expected.
The code is simpler because all data is just stored as attributes, but
also different because the point data for all curves is stored in the same
arrays.
Similar performance improvements as other commits in T95443 are
expected, expecially for cases where there are many small curves.

This commit ports the "Set Spline Type" node to the new curves type.
Performance should be improved in similar ways to the other refactors
from the conversion task (T95443). Converting to and from Catmull Rom
curves is now supported. There are a few cases where a lot of work can
be skipped: when the number of points doesn't change, and when the
types already match the goal type.
The refactor has a few other explicit goals as well:
- Don't count on initialization of attribute arrays when they are
first allocated.
- Avoid copying the entire data-block when possible.
- Make decisions about which attributes to copy when changing curves
more obvious.
- Use higher-level methods to copy data between curve points.
- Optimize for the common cases of single types and full selections.
- Process selected curves of the same types in the same loop.
The Bezier to NURBS conversion is written by Piotr Makal (@pmakal).

A field input node for the scale of each top-level instance transform.
The scale can be set with the "Scale Instances" node, but previously
could not be retrieved.

A field input node for the rotation of each top-level instance transform.
The rotation can be set with the "Rotate Instances" node, but previously
could not be retrieved.

The original assert did not take into account the offset size in the loop being -1. The tests were then run in non-debug mode, so while the mesh regressions still passed, the false positive asserts that happened were not caught.

The separate geometry and delete geometry nodes often invert the
selection so that deleting elements from a geometry can be implemented
as copying the opposite selection of elements. This should make the two
nodes faster in some cases, since the generic versions of selection
creation functions (i.e. from d3a1e9cbb9) are used instead
of the single threaded code that was used for this node.
The change also makes the deletion/separation code easier to
understand because it doesn't have to pass around the inversion.
The original index layer was not initialized properly.
Supporting original indices properly for this node is
doable, but for now it is better to simply initialize them
to the "none" value to fix the crash.

Code was using the loop [which is looping over the selection] index as
an index for the lookup into the edges directly, but needs to be a
lookupinto the IndexMask.
Also renamed the variable (as used elsewhere) to make this more clear.
If accepted, would be nice to still get this into 3.2.

The issue was that the extend socket (the last empty socket in
Input/Output nodes) was repeatedly removed and added again,
which caused more updates than necessary. Now, the extend
socket is kept if it existed already.

This commit hides "UI attributes" described in T97452 from the UI lists
in mesh, curve, and point cloud properties, and disallow accessing them
in geometry nodes.
Internal UI attributes like selection and hiding values should use the
attribute system for simplicity and performance, but we don't want to
expose those attributes in the attribute panel, which is meant for
regular user interaction. Procedural access may be misleading or cause
problems, as described in the design task above.
These attributes are added by two upcoming patches: D14934, D14685

This is a follow up to rBbb0fc675822f313c5546a2498a162472c2571ecb.
Now the same kind of run-time data is added to nodes and sockets.

This results in a speedup if the capture attribute is only needed
under specific circumstances (e.g. when a switch further down the
line is true). Previously, the input field was always evaluated.

* Port over new code tables from Cycles
* Convert Rec.709 to scene linear for lookup table.
* Move code for wavelength and blackbody to IMB so they can access the
required transforms, which are not in blenlib.
* Remove clamping from blackbody shader to bypass the texture read.
Since it's variable now easiest to just always read from the texture
than pass additional parameters.
* Fold XYZ to RGB conversion into the wavelength table.
Ref T68926
* Rename ambiguous rgb to scene_linear in some places
* Precompute matrices to directly go to scene instead of through XYZ
* Make function signatures more consistent
This patch changes the Text Box Width socket to always have that label
instead of switching to "Max Width" when Overflow mode is picked.
