This upgrade for DPC++ and its dependencies brings several
bug fixes and also eliminates some patches and backports
that are now obsolete with this new release.

How solid/faded the edges of a Grease Pencil stroke is
controlled by the `softness` attribute. This change adds a
node that exposes that attribute, allowing the user to
control it via Geometry Nodes.

When strip is added, operator first finds "best" channel to place a
strip in, then adds new strip to that channel and finally does check if
the strip is overlapping other strips. If it does, it handles the
overlap.
To prevent adding strip to locked or muted channel, fix has to be done
at 2 places:
- `sequencer_generic_invoke_xy_guess_channel` which finds the "best"
channel
- `transform_seqbase_shuffle_ex` which handles overlap.
Further check for free channels was added to all strip add operators.
If there is no space above channel, that user selected, error is
displayed and operator is cancelled.
Note, that `transform_seqbase_shuffle_ex` is used only for resolving
overlaps where strip position in time must stay constant, so it moves
the strips in Y axis. This PR does not affect user selectable
`overlap_mode`.

Also rename "blender export import test suite description.txt" to
"readme.txt" as the filename was including information available
in the leading path.
Node sockets have many different aspects that affect their visibility and
whether they are grayed out. This patch cleans up the methods used to check if
sockets are visible and adds descriptions that should make it more obvious which
ones should be used.
This also fixes a few places where the wrong method was used which is more
obvious now.

The main goal of this patch is that the column widths and ordering is not reset
every time one switches between different contexts.
It does that by keeping track of multiple `SpreadsheetTable`. There is one for
each table that is viewed (so e.g. the point and edge domain of the same mesh
are two different tables). Each table has an identifier and an array of columns.
There is some garbage collection in place so that the number of stored tables
does not increase unbounded.
This also comes with an updated Python API:
```python
import bpy
spreadsheet = bpy.context.screen.areas[...].spaces.active
active_table = spreadsheet.tables.active
print(active_table.id.type)
print(active_table.id.attribute_domain)
print(active_table.columns[0].id.name)
```
In the future, we might add some smarter logic to keep tables with different
identifiers more in sync. We don't have a great heuristic for that yet.

The script check_source/static_check_size_comments.py run directly
or called via the convenience target "make check_size_comments".
Add a utility module: `line_number_utils` which implements
a version of `re.finditer` that includes line numbers & ranges.
Compositor node sockets should be updated when toggling grease pencil
pass in the pass list. It was missing a `rna_ViewLayer_pass_update`, now
it will work as expected.

In the Python API, helper function `gpu_extras.presets.draw_texture_2d`
still used batch type `TRI_FAN`, which is deprecated since Blender 3.2.
In this patch the batch type is changed to `TRIS`.

Reduces the number of parameters passed in `sculpt_undo.cc`,
additionally the `const` specifier is misleading here, as the
`SculptSession` is modified via the `Object` reference.

The topology automask setting uses the active vertex when precomputing
the cache at the beginning of a stroke. This value can be invalid when
the brush stroke doesn't start on the mesh.
For example, this can happen with brush strokes that use a projected
instead of spherical falloff due to more BVH nodes being included in the
initial coarse check.
To fix this, simply check for the existence of the active vertex and
early exit if it is not valid.

This was an alternative way to write properties for layout operator buttons,
for the most cases are more than enough to use the returned pointer.
There were just 2 cases where this was useful, the quick access menu
that reuses operator property values, this now overrides the id property group
data pointer generated for the operator, also for `uiItemsFullEnumO_items`.

Cleanup and simplification of GPUMaterial and GPUPass compilation.
See #133674 for details/goals.
- Remove the `draw_manage_shader` thread.
Deferred compilation is now handled by the gpu::ShaderCompiler
through the batch compilation API.
Batch management is handled by the `GPUPassCache`.
- Simplify `GPUMaterial` status tracking so it just queries the
`GPUPass` status.
- Split the `GPUPass` and the `GPUCodegen` code.
- Replaced the (broken) `GPU_material_recalc_flag_get` with the new
`GPU_pass_compilation_timestamp`.
- Add the `GPU_pass_cache_wait_for_all` and
`GPU_shader_batch_wait_for_all`, and remove the busy waits from
EEVEE.
- Remove many unused functions, properties, includes...

Use a similar convention for struct member identifiers,
(the identifiers without surrounding spaces). This allows the values
to be scanned and validated.
When enabled, this normalize the strength by the light area, to keep
the total output the same regardless of shape or size. This is the
existing behavior.
This is supported in Cycles, EEVEE, Hydra, USD, COLLADA.
For add-ons, an API function to compute the area is added for conversion,
in case there is no native support for normalization.
area = light.area(matrix_world=ob.matrix_world)

Similar to other renderers, this adds a temperature property to set the
light color using blackbody emission. This can be more convenient than
using nodes, and can improve interop with other software.
This is supported in Cycles, EEVEE, Hydra, USD, COLLADA and FBX.
Pull Request: https://projects.blender.org/blender/blender/pulls/134303
Similar to other renderers, this adds an exposure property to multiply
the light power by 2^exposure. This can be more convenient to control
a wide range of values.
This is supported in Cycles, EEVEE, Hydra, USD, COLLADA and FBX.

This has been causing some confusion because it is in radiometric units
rather than photometric, which is how real world lights are typically
specified. With the addition of exposure and normalize options this
also becomes less clear.
Ref #134528
Update the Python API documentation about crashes with multi-threaded
code.
- Move the "threading gotcha" into a file of its own. That way it's
immediately clear from looking at the Gotcha table of contents that
threading is not supported.
- Simplify the example code, so that it doesn't access `bpy`.
Apparently the problem is much wider than just multi-threaded access
to `bpy`, and involves _all_ Python threads, regardless of what they
do / access.
- Add some more explanation and move some text from the bottom to the
top, so that the first-read part (when reading top to bottom) has
most of the information.

As noted in the removed comment, python has better
syntax for assigning operator properties values, as:
``` py
op = layout.operator('my_operator')
op.string_prop = "value"
```
Code has been unused since e0fc6d0c33

This PR adds a global mutex to `path_create_directories` to fix a thread-safety issue which can occur when concurrently creating multiple subdirectories with common stems.

Previously, we were drawing the context path in the header of the spreadsheet.
However, that had some problems:
* When using a viewer that's somewhere deep in a node group, the viewer path
wouldn't fit.
* Standard editor menus didn't fit in. Also we wanted to add spreadsheet
specific operators that should be in a new menu.
* Couldn't fit more useful data for the context path (like the inspection index
for repeat zones).
This patch solves this by moving the entire context path to the left side bar.
This frees up the header for menus.
The new context panel information is added at the top of the side bar because
then there is a proper hierarchy: `Object > Evaluation State > Viewer Path
(optional) > Instance Selection > Domain Selection`
This patch also adds information about the current inspection index for for-each
and repeat zones. They are not editable yet, but that can be implemented
separately as it might require a few more changes for everything to update
correctly.
The new Viewer Path panel is only displayed when actually showing viewer data.

The stencil value was also considered and could lead to out of range
depth values. These were ignored by operators and could lead to
printing errors, canceling operators, or inaccurate depth
selection.
This is a NVIDIA only issue as these GPU support DEPTH24S8 textures.
We should consider defaulting to DEPTH32FS8.

In detail:
- Direct accesses of state attributes are replaced with the INTEGRATOR_STATE and INTEGRATOR_STATE_WRITE macros.
- Unified the checks for the __PATH_GUIDING define to use # if defined (__PATH_GUIDING__).
- Even if __PATH_GUIDING__ is defined, we now check if the feature is enabled using if ((kernel_data.kernel_features & KERNEL_FEATURE_PATH_GUIDING)) {. This is important for later GPU ports.
- The kernel usage of the guiding field, surface, and volume sampling distributions is wrapped behind macros for each specific device (atm only CPU). This will make it easier for a GPU port later.
If the `transdata_check_local_islands` check does not succeed, we end up
with `CTX_NO_PET` for scaling/rotation.
For `Grease Pencil`, this was lost in the transition from GPv2 > GPv3
(type was renamed to "legacy", then removed from
`transdata_check_local_islands` in a804320138, but the new type was
never added).
Curves never specified support for this, but both types are (in theory)
taking into account `V3D_AROUND_LOCAL_ORIGINS` in
`curve_populate_trans_data_structs` (logic from 9d86fada03 might be a
bit broken for proportional editing "islands" without anything selected
as reported in #139101, but that will be corrected in another PR).
So to resolve, add `Grease Pencil` and `Curves` as supported object
types in `transdata_check_local_islands`
NOTE: `transdata_check_local_center` already has these two types as
well.
