Follow-up fix for #113330.
The `valid_socket_type` classmethod in node trees is only available on
custom node trees (but documentation does not say that). It cannot be
used to determine if the default float socket type is valid for built-in
node tree types. We have to assume this socket type is always valid for
built-in node trees, or the operator will try to call a non-existent
method.

Cycles implements the "Taming the Shadow Terminator" paper by Matt Jen-Yuan
Chiang to solve shadow terminator issues when a bump map is applied, as well
as similar approach for the glossy reflection to ensure ray does not get
reflected to inside of the object.
This correction term is applied unconditionally, which makes it harder to have
full control over shading via normals for stylistic reasons.
This change exposes this corrective term as an option called "Bump Map
Correction" which is available in the shader settings next to the
"Transparent Shadows".
The reason to make it per-shader rather than per-object is to allow flexibility
of a control: it is possible that an object has multiple shaders attached to it,
and only some of them used for bump mapping. Another, and possibly stronger
reason to have it per-shader is ease of assets control: shader brings settings
which are needed for its proper behavior. So if material at some point
decides to take over normals, artists would not need to update settings on
every asset which uses that material.
The option is enabled by default, so there is no changes for existing setups.

CYCLES_ONEAPI_SPIR64_GEN_DEVICES -> CYCLES_ONEAPI_INTEL_BINARIES_ARCH
so it's more aligned with the name for the other backends, such as
CYCLES_CUDA_BINARIES_ARCH.
The first public Windows driver version with a higher number is
101.4824, so we bump the min-required driver version on Windows to this
one to ensure compatibility.

Above commit checks an existing nameproperty for collection items, but
it does so in a way that it only checks the "parent" type. If these are
"subclassed" though, we might not have the nameproperty defined on the
"parent" class (but on the subclass instead).
Code would then error out with e.g. "FreestyleLineStyle.color_modifiers
does not support string lookups".
In the case of the report the following happened.
- linestyle modifiers (`LineStyleModifier`) can be any of:
-- `color_modifiers` / `LineStyleColorModifier`
-- `alpha_modifiers` / `LineStyleAlphaModifier`
-- `thickness_modifiers` / `LineStyleThicknessModifier`
-- `geometry_modifiers` / `LineStyleGeometryModifier`
But all of the above have subtypes, e.g.
`LineStyleColorModifier_AlongStroke`,
`LineStyleColorModifier_DistanceFromCamera`, ...
Currently, the `nameproperty` is not defined e.g. on the
`LineStyleColorModifier` (but instead on the subtypes).
Prior to 6a49041be3 (without
`RNA_property_collection_lookup_string_has_nameprop` in place),
`pyrna_prop_collection_subscript_str` could still actually find the
nameprop because it iterates into the collection and got it on the
actual Item (`LineStyleColorModifier_DistanceFromCamera` instead of
`LineStyleColorModifier`).
So while it might be possible to refine
`RNA_property_collection_lookup_string_has_nameprop` to descend into
subclasses (I didnt find an obvious way though other than scanning all
existing modifiers [not modifier types -- we would need a way to find
all types that inherit from e.g. `LineStyleColorModifier`] which kind of
defeats the purpose of checking this early), this PR moves the name
definition from the subclass to the parent class (so way from
`rna_def_modifier_type_common`) -- and this way,
`RNA_property_collection_lookup_string_has_nameprop` can properly pick
up the nameprop. It does a bit of code duplication though.

The crash was happening because the storage buffer for active smoothing
was not resized correctly as the active smoothing window changed.
This fix makes sure the storage buffer is resized correctly.
The issue was that custom data layers were modified without checking
that the data was not shared. Now the data is unshared first.
I also added an assert to catches this kind of issue more directly.

You can now type to search directly in the `Add` menu.
Bit unfortunate though that this is not mapped to any shortcut in the
`Industry Compatible` keymap anymore
I think we could just add TAB back (but this time, mapped to
`NODE_MT_add`).

Exposed by cba9f47562 (but actually caused by 4d668e6825 I think).
Because of 4d668e6825 , the `StripDrawContext` `content_start` &
`content_end` were wrong for hold still regions.
These wrong extends were then used in cba9f47562 .
Now actually update `StripDrawContext` `content_start` & `content_end`
when hold still regions are in play (instead of just calling the right
functions [but not using their return values]).

Set the "I/O error" if the result from read is larger than the requested
size, while unlikely - set the error so an error return always sets the
`errno`.
Pass the mesh to the drawing functions so it doesn't have to be
retrieved from the PBVH. It's nice to rely less on the PBVH `me`
pointer, since it's a fairly ugly "back pointer" which isn't necessarily
good design.
Making some liboverride local will break/corrupt liboverride hierarchies
in many cases. So that function (or its caller, in some cases) need to
call #BKE_lib_override_library_main_hierarchy_root_ensure to re-validate
(and re-generate if needed) the liboverride hierarchy roots.
The code ensuring a valid liboverride hierarchy root ID pointer for all
liboverrides in a given Main would fail in some cases, and crash on
asserts (in Debug builds) or due to corrupted data later in code
(release builds).
The main issue fixed here is re-entry in case of dependency loops (a
same ID being checked more than once within the same chain of recursive
calls to ensure its hierarchy root is valid). Solved the usual way now,
using the intermediate 'PROCESSING' flag instead of setting immediately
the 'PROCESSED' one, when recursively processing the chain of
dependencies.
A second issue fixed in that code was that in some cases, it could leave
the invalid existing hierarchy root pointer unchanged, because it could
not find a 'valid enough' alternative.
NOTE: This data corruption is presumably caused by 'make local'
operations on liboverride hierarchy root IDs. This will be addressed as
a second commit.
For reference, issue is reproducible when opening
`/promo/splash/040_0010.lighting.splash.blend` from Pets SVN repo r3106.
This implements the core changes for this design: https://devtalk.blender.org/t/grease-pencil-integration-into-geometry-nodes/31220
The changes include:
* Add `CustomData` for layer attributes
* Add attribute support for the `GreasePencilComponent` to read/write layer attributes. Also introduces a `Layer` domain.
* Implement a `GreasePencilLayerFieldContext` and make `GeometryFieldContext` work with grease pencil layers.
* Implement `Set Position` node for `Grease Pencil`.
Note: These changes are only accessible/visible with the `Grease Pencil 3.0` experimental flag enabled.
