* Move colorband and theme DNA to own headers
* Move some anim, curve, modifier and space enums to new headers
* Move data transfer enums to DNA
* Duplicate imbuf proxy and GPU backend enums
For a few reasons:
* Reduce number of includes in DNA headers
* Don't define enums used in DNA outside of DNA
* Move theme settings to separate header for userdef_default_theme.c
* Prepare for using default initializers in DNA headers. (#134531)

Previously spell checker ignored text in single quotes however this
meant incorrect spelling was ignored in text where it shouldn't have
been.
In cases single quotes were used for literal strings
(such as variables, code & compiler flags),
replace these with back-ticks.
In cases they were used for UI labels,
replace these with double quotes.
In cases they were used to reference symbols,
replace them with doxygens symbol link syntax (leading hash).
Apply some spelling corrections & tweaks (for check_spelling_* targets).
Prevent dissolve leaving duplicate faces when dissolving edges.
Also use the builtin reuse of duplicate faces provided by BM_face_join()
instead of doing it manually.
Ref: !137634
Every call to BM_faces_join and BM_faces_join_pair has been adjusted to
provide the new face pointer, and a BLI_assert_msg has been added so
that doubles are now consistently identified and flagged as a problem.
BM_faces_join is now also capable of automatically reusing a double
when it is found. This new behavior is currently unused at this point.
Future patch-sets will begin to use it, allowing simplification of
calling functions.

This fixes most "One Definition Rule" violations inside blender proper
resulting from duplicate structures of the same name. The fixes were
made similar to that of !135491. See also #120444 for how this has come
up in the past.
These were found by using the following compile options:
-flto=4 -Werror=odr -Werror=lto-type-mismatch -Werror=strict-aliasing
Note: There are still various ODR issues remaining that require
more / different fixes than what was done here.

The existing behavior of the grid fill operator requires a loop of
boundary or wire edges to be selected. This algorithm tries to fit a
grid of quads into the edge loop. It also works if you select two of the
four 'rails' of an edge loop.
This new behavior allows running grid fill after selecting faces.
If the algorithm sees that a set of faces are selected, it separates
all the faces, and then attempts to grid from their exterior boundary
using the exact same logic it normally uses for interior boundaries.
This all assumes the user has selected a set of faces with an outside
border that works with grid fill. (has one clear exterior loop with an
even number of edges) If not, grid fill will halt, and notify the user
of the error, exactly the way that it already did before.
Once the grid fill is complete and successful,
the existing faces which were replaced get deleted.
UVs (including at UV island boundaries) are interpolated properly,
as are custom-data on verts, edges, faces, and face corners.
At the edges of the selection, the edges/faces/face corners that are
selected contribute, but the custom-data outside the selection does not.
This also resolves non-deterministic behavior.
The previous behavior of `edbm_grid_fill_prepare` found the vertex with
the largest angle, then walked the edge loop until it found one out of
the three best remaining corners. This established one edge of the grid
area, and the second edge was found by symmetry.
However, the direction that the algorithm walked the loop
(and therefore which second corner was found) was essentially arbitrary.
The new behavior first finds the vert with the largest angle,
then finds the vert with the second largest angle,
(after excluding the diagonally opposite corner from the first vert),
and selects the edge between those two verts.

When using clangd or running clang-tidy on headers there are
currently many errors. These are noisy in IDEs, make auto fixes
impossible, and break features like code completion, refactoring
and navigation.
This makes source/blender headers work by themselves, which is
generally the goal anyway. But #includes and forward declarations
were often incomplete.
* Add #includes and forward declarations
* Add IWYU pragma: export in a few places
* Remove some unused #includes (but there are many more)
* Tweak ShaderCreateInfo macros to work better with clangd
Some types of headers still have errors, these could be fixed or
worked around with more investigation. Mostly preprocessor
template headers like NOD_static_types.h.
Note that that disabling WITH_UNITY_BUILD is required for clangd to
work properly, otherwise compile_commands.json does not contain
the information for the relevant source files.
For more details see the developer docs:

Rotating an edge deletes the edge and creates a new edge
however these edges were being iterated over and had their indices
checked.
In practice this wasn't causing use-after-free errors because the
edges are part of a BLI_mempool, nevertheless using freed elements of a
memory-pool should be avoided.
- Replace blender::Map with an array to lookup heap-nodes by edge index.
- Only create the array when the topology influence is used.
These gives ~5-9% overall speedup to operator function.
In C++, in most cases empty braces (aka value initilization) are
the best way to initialize to 0/null (or the default values if
specified in the class/struct declaration).
Replace 3x arguments and a return value with a structure
that stores the neighboring edges & loops.
Also call add_without_duplicates from a loop instead of inlining.
A new parameter, topology influence, is added that causes the
join_triangles operator to prioritize edge joins that create quads with
sensible geometry relative to existing quads, instead of selecting the
'flattest' and 'squarest' next pair and then leaving leftover triangles
with no partners to merge with.
This produces its best results with the face and shape thresholds set to
180 degrees (no hard limits as a restriction against merging) and
topology influence somewhere between 100-130%, depending on the mesh.
Too low and many parallelograms and triangles are left, too high and the
algorithm tries too hard and starts making errors.
Note that both quads already present in the selection, as well as the
quads that are generated during the operator, will influence the
topology around them. This allows the modeler to manually merge a few
quads in key areas of the mesh, as a hint to the algorithm, indicating
what result they way they want to see, and the algorithm will then take
those quads into account and try to build around them according to the
modeler's guidance.
A new checkbox to leave only the remaining triangles selected has also
been added. This helps users visualize what remains to be fixed.

As of 2a56403cb0, bevel weight data is stored as a generic
attribute. The bevel modifier is currently hard-coded to use the
`bevel_weight_edge` attribute as the data source for the weights.
This commit adds a string textbox where the user can specify alternate
attributes for the bevel's edge weights.
The string name field is added as a search button which provides a list
of all attributes in the original mesh. This is meant to work similarly
to geometry nodes, so mismatched attribute data types and domains are
automatically converted/interpolated as necessary. Attributes created
by previous modifiers can also be used, but they won't appear in the
search menu.

The attribute API defined in `attribute.cc` was dependent on
the assumption that `ID`s are always the "direct" owners of attributes.
For Grease Pencil drawings, this is not the case. The Grease Pencil ID
stores the attributes for layers, and the attributes for drawings are stored
in `CurvesGeometry` on the drawings themselves.
In order to make use of `rna_attribute.cc`, we need that API to handle
other types of attribute owners.
This adds an `AttributeOwner` which is basically just a type and a
pointer. We replace the `ID` pointers and pass `AttributeOwner`s instead.
For cases where we have to do a switch based on the type, all the
types are handled and the `default` statment is left out. This ensures
that we get a compiler warning when a new `AttributeOwnerType`
is added.
No functional changes expected.

Along with the 4.1 libraries upgrade, we are bumping the clang-format
version from 8-12 to 17. This affects quite a few files.
If not already the case, you may consider pointing your IDE to the
clang-format binary bundled with the Blender precompiled libraries.
Except for vertex groups and a few older color types, these
are generally replaced by newer generic attribute types.
Also remove some includes of DNA_mesh_types.h, since it's
included indirectly by BKE_mesh.hh currently.
Remove most includes of this header inside other headers, to remove unnecessary
indirect includes which can have a impact on compile times. In the future we may
want more dedicated "_fwd.hh" headers, but until then, this sticks with the
solution in existing code.
Unfortunately it isn't yet possible to remove the include from `BKE_geometry_set.hh`.
The version of BM_elem_attrs_copy that took a map used a reference
the version without a map didn't, which is fairly confusing.
Pass by pointer now unless this is part of a wider refactor
to move to references everywhere.
