BKE link/append: Add optional blendfile handle to libraries.

This enables calling code to deal with the blendfile handle themselves,
BKE_blendfile_link then just borrows, uses this handle and does not
release it.

Needed e.g. for python's libcontext system to use new
BKE_blendfile_link_append code.

Part of T91414: Unify link/append between WM operators and BPY context
manager API, and cleanup usages of `BKE_library_make_local`.

Fix T93092: incomplete animation rendering of multi-layer exr composition

This was broken by rB0c3b215e7d5456878b155d13440864f49ad1f230.
The caching of loaded exr files needed some special treatment.

Fix T92654: missing padding in spreadsheet cells

This was probably broken by rB5c2330203e11e0d916960218b07d88d2193bf526.
For now just add the padding back in a spreadsheet specific way.

Fix T93090: crash with data transfer modifier and geometry nodes

There was a missing normals layer that was requested by the data transfer
modifier from the target object. The normal layer was correctly added to
the target object. However, it never reached the data transfer modifier
because the mesh was copied in `BKE_object_get_evaluated_mesh`
(in the call to `get_mesh_for_write`) and the copy does not include the normals
layer.

The solution is to not use `get_mesh_for_write` here which was only used
because `BKE_object_get_evaluated_mesh` returns a non-const `Mesh *`.
Mid term, it should actually return a `const Mesh *` to avoid the confusion.

Fix T93194: greasepencil channel lists ignoring collection visibility

Same fix as rB0a3b4d4c64f1, but this time for greasepencil.

To repeat: dopesheet in greasepencil mode was ignoring the temporariy
visibility flag of collections. As a result, even though the dopesheet
was supposed to show animation data of visible greasepencils only was
still showing such data of greasepencils that were hidden by hiding
their collection.

Fix T89260: Eevee crashes with custom node sockets.

Cause of this issue is that Custom Node Sockets info type was
initialized as SOCK_FLOAT when registering. Areas within the core that
would ignore custom socket types by checking its type would use the
socket as being a float type.

When custom node sockets have a property called default_value blender
tries to store it as an internal default value what failed in debug
builds.

This patch will set the socket type to SOCK_CUSTOM when registering a
custom socket type and allow, but skip storage of custom default values.
In this case the default values should already be stored as custom
properies.

Fix T92384: Wrong UV layers used with Boolean Modifier (Fast Solver)

Ensure the layers from the source mesh are used instead of the

appropriate.

VSE: Add drag and drop handler for preview area

For some users, dropping assets into preview area may be more practical
due to space constraints or it may be just more intuitive.

VSE: Support drag and drop for datablocks

For using the Outliner and/or the Asset Browser as scene independent
tools to organize a/v source material is necessary for the users to be
able to drag and drop data blocks into the VSE. This was also an
unfulfilled design target for the Outliner Gsoc project.

Datablocks won't be used directly. Path to file will be passed to strip
add operator instead.

Assets: Generate light preview when making light object an asset

We already supported previews for lights, just didn't actually use them
when making a light object an asset. They were only used when making the
light data itself an asset.
