Cleanup: use "use_" prefix for boolean types

Curves: Avoid duplication of control points during evaluation

This commit avoids duplicating the deformed control point
list twice by modifying the list in the object curve cache directly.

For curves, the original control point data was duplicated into a
local listbase, deformed, used to create the "bevel list" data, and
then duplicated again for the object-level storage of deformed
control points. Text objects and surface objects had a similar
unnecessary duplication.

Cleanup: Avoid freeing curve evaluation data twice

The curve bevel list was freed, and then freed again in a call to the
function that recalulates it. The curve "anim path" data was freed
only to be freed again in its calculation function as well. Also move
the anim_path calculation directly after the bevel list creation to
make its requirements more explicit.

Cleanup: Split curve and surface data evaluation functions, rename

Surface objects were already handled by an early return in the main
"curve types" function. This commit splits them, renames the funtions
to match (and be more consistent with other names), and sanitizes the
checking of object types.

Cleanup: Order return arguments last, use r_ prefix

Cleanup: clang-tidy

Cleanup: resolve discarded-qualifier warning

Fix T89465: Loss of mouse movement when window left with pen.

When a window is left with a WinPointer pen, the inrange check
prevents resetting pen info.

Cleanup: Avoid ASAN report when converting displist to mesh

Don't call `memcpy` with a null destination (and 0 size).

Cleanup: Replace paranoid check with assert

Every call to `BKE_displist_make_curveTypes` already checks the object
type beforehand, there is no need to check it again. Also removed an
outdated comment.

Cleanup: Remove unused "for_orco" argument to curve evaluation

`BKE_displist_make_curveTypes` had a `for_orco` argument that was
always false in calls to the function. Removing it allows the curve
displist and modifier evaluation code to become simpler. There are
some related cleanups in rBdf4299465279 and rB93aecd2b8107.

Cleanup: Add function to create a CurveEval from a nurbs list

Sometimes the current spline list isn't part of the original curve, like
when using the deformed control points, etc. This will be helpful in
the curve modifier stack.

Curve: Add functions to retrieve const access to spline list

While the const correctness of `ListBase` is quite limited, it's helpful
to have a way to retrieve the `Nurb` list from curve object data without
casting away const from the curve.

Cleanup: Use const arguments

UI: Do Not Resize Already-Open Temporary Windows

There is no longer a need to resize windows that are _already_ open,
since temporary windows can no longer take over the space used by other
already-open temporary windows. This primarily affects Preferences and
Render windows.

Fix T89515: Clicking on Favorites in File Browser will rename them

Likely uncovered by 6c97c7f767c9, the actual mistake would be from
6942dd9f4900.

The hacks to display text buttons for renaming in UI-Lists used the emboss of
the text button for handling logic. It relied on the emboss `NONE` but we also
introduced `NONE_OR_STATUS` with 6942dd9f4900. Both values need to be treated
equally for the logic of this hack to work.

The change in `interface_layout.c` is actually not needed for this exact issue,
but it's the correct thing to do. There may actually be more cases where `NONE`
and `NONE_OR_STATUS` need to be treated equally. Something to be checked still.

Fix T89516: Crash on append

Caused by 37458798fa02, was doing a NULL-pointer dereference because it used
the wrong pointer to check if the data-block is linked.

Fix T87194: custom attributes not accessible with Cycles Volume

Custom properties defined on objects are not accessible from the
attribute node when rendering a volume in Cycles. This is because
this case is not handled.

To handle it, added a primitive type for volumes in the kernel,
which is then used in the initialization of ShaderData and to
check whether an attribute lookup is for a volume.

`volume_attribute_float4` is also now checking the attribute
element type to dispatch to the right lookup function.

Fix T89449: File Browser preview image not responsive to click

Logic in the main `switch` for button handling was wrong and would execute for

LibOverride: Fix crash in ShapeKeys when making a mesh override local.

Weird 'embedded for overrides' flag of embedded IDs (including ShapeKeys

Reported by studio, thanks.
