UI: Improved "Area Close" Neighbor Selection

The new "Close Area" operator can let any neighbor replace the area to
be closed. This patch improves the selection of the best, and most-
aligned, neighbor. It maximizes the ratio of the shared edge lengths,
rather than minimize the absolute amount of misalignment. This follows
our expectations closer because it takes into account the relative
sizes of the areas and their edges.

see D11143 for details and examples.

VSE: Fix meta strip boundary can not be changed

In e1f3996d740c, logic for changing metastrip start and end frame based
on contained strips was removed. This was done intentionally and
incorrect functionality wasn't noticed as drawing code reflected
seemingly correct state.

Original code was mostly correct, because meta strip doesn't store its
internal start and end points. This code was restored with minor
modifications so function `SEQ_time_update_sequence()` is fully self
contained as it is used not only by transform operator.

In addition, drawing glitches that happen when meta content is outside
of meta boundaries were fixed. These glitches were not caused by
e1f3996d740c.

Fix T88194: Animation player displays washed out colors

Byte images used `ibuf->float_colorspace` as source colorspace.
This was oversight - `ibuf->rect_colorspace` should be used as source

VSE: Fix disk cache potentially overwriting blend file

When disk cache path is same as blend file path, with Unix-like systems
blend file can be overwritten by disk cache directory.
This was caused by `BLI_delete(path, false, true)` when path points to
file. On Windows this would result in error message and file would not
be deleted. On Linux, file is deleted and then overwritten with cache
directory.

To further minimize chance of removing blend file, append disk cache
path with `_seq_cache` suffix.

Cleanup: Simplify public/private specifiers

By rearranging a few variables we can remove redundant specifiers

Cleanup: Splines: Add accessors to spline vector

Not allowing external direct access to the vector of splines in the
curve will help for things like reallocating custom data when a spline
is added or removed.

UI: Colors for Texture/Material node sockets and small tweaks

* Set colors for the new texture and material sockets
* Material uses the same color used for shading icons
* Texture uses a plum color desaturated enough to not be confused with Vector's violet
* Image socket adjusted to be closer to Texture sockets but darker
* Integer socket toned down in saturation to not stand out so much
(and be closer to float sockets which are gray)

Making this change now during bcon1 to gather feedback from the community,
and because Geometry Nodes needs to use the new texture/material sockets.

Geometry Nodes Curves: Expose first builtin point attributes

This commit exposes the first spline control point attributes. The
implementation incorporates the attributes into the virtual array
system, providing efficient methods to flatten the data into a
contiguous array and to apply changes from a flattened array. This
is only part of the eventual goal, which includes changes to run
attribute nodes separately for each spline to completely avoid copying.

So far `tilt` and `radius`, the two generic attributes common to
all spline types, are implemented. The more complex `position`
attribute is also added. It requires some special handling for Bezier
splines, where the control point handles need to be moved along with
the control points. To make that work I also added automatic handle
recalculation to the Bezier spline.

Fix T87851 EEVEE: Performance regression with baked lighting & transparency

This was caused by the drivers not optimizing the shader enough to remove
the samplers and data used by closure eval. Removing the lighting loops
from the depth shader fixes the perf regression.

Fix T81247: Constrain selected UVs to correct UDIM

With Constrain to Image Bounds selected, UVs will be constrained to the
correct/closest UDIM if the image is tiled.
UVs will be constrained to the 0-1 UV space if the image is not tiled.
This will override the present behavior of always constraining selected
UVs to the 0-1 UV space (UDIM 1001).
