Buildbot: Cleanup, typo in logging

Fix issue with uint in headers in recent own commit.

Would break on some systems/compilers...

Fix (unreported) wrong size of UserPreferences' `dupflag` parameter.

Adding volume obdata option to `eDupli_ID_Flags` enum made it go beyond
the 16 bits of a short... Also, enums should typically be stored in
unsigned integers.

Cleanup: use explicit enum type for duplicate option of `BKE_object_duplicate`

Using enum type itself in implementations, and uint in headers (as using
enums types in headers is a pain when enum are not defined and used in a
single same header file...).

Cleanup: remove hierarchy parameter from `BKE_collection_duplicate`

It makes no sense to deep-copy a collection and not also copy its
children collections... Parameter was not used anymore anyway.

So now this duplicate function will always at least deep-duplicate all
of its children collections, recursively.

Cleanup: get rid of `BKE_collection_copy`.

We want to get rid of those for all ID types ultimately, but that one
was only used in one place, being the only one calling
`BKE_collection_duplicate` without hierarchical duplicate and parent
collection pointer, effectively using the full power of the complex deep
duplication code for a mere `BKE_id_copy` call...

This will allow for further cleanup in duplicate code.

Refactor: move .blend read/write of mesh deform modifier to MOD_meshdeform.c

Cleanup: remove unnecessary indirection for .blend read/write of curvemapping

Refactor: Move curvemapping .blend read/write to blenkernel

This is necessary so that it can be accessed from `blendWrite`
and `blendRead` callbacks from modifiers.

Functions: Multi Function

This adds the `MultiFunction` type and some smallish utility types that it uses.
A `MultiFunction` encapsulates a function that is optimized for throughput by
always processing many elements at once.

This is an important part of the new particle system, because it allows us to
execute user generated node trees for many particles efficiently.

Fix bitscan_reverse_uint on MSVC compiler

Was a mistake from the very beginning of implementation.

GPencil: Convert and Bake mesh animation to grease pencil strokes

This patch adds two options:

- Convert a mesh to grease pencil strokes.
- Bake the mesh animation into grease pencil strokes.

Both are related and must be included in the same patch.

Related to tasks: T77629 and T77630

Notice: The conversion is done for mesh edges and it's not considering any visibility clipping. All edges are exported, no matters if it's visible or not.

Example of Convert a Mesh to Grease Pencil strokes:

This conversion was inspired by the technique used by @luamono in this tweet: https://twitter.com/luamono/status/1239983662176841730

Example of Bake Animation (the video is a little outdate, but the basic functionality is the same, only small changes in UI):

Fix T77803: IK Degrees of freedom drawing glitch

IK degrees of freedom is rendered using wires and a solid sphere. The
solid used the wireframe drawing what resulted into drawing glitches.
This patch adds a new shader to draw the solid shape.

Buildbot: Support multiple workers talking to single codesign server

Is achieved by replacing hard-coded signed/unsigned file names with
"<uuid>" which acts as a "request ID". This way multiple workers can
put their requests into a single directory without collisions. The
code sign server will handle the requests sequentially in an unknown
order.

Buildbot: Don't use builder name in the build directory

The directory layout on worker goes as following:

<Worker>
<Builder Name>
blender.git/
build/
install/
lib/

Adding an extra <Builder Name> after build is redundant.

CMake: Fix compilation errors related on missing dna_type_offsets.h

Some of the files were (indirectly) using dna_type_offsets.h without
adding dependency from bf_dna (which is needed to ensure the file is
generated prior to library compilation).
