MetaBall: optimize memory allocation for meta-ball tessellation

Double the allocation size when the limit is reached instead of
increasing by a fixed number.

Also re-allocate to the exact size once complete instead of over
allocating. This gives a minor speedup in my tests ~19% faster
tessellation for ~1million faces.

Fix meta-ball bound-box calculation reading past buffer bounds

This broke "test_undo.view3d_multi_mode_select" test in
"lib/tests/ui_simulate" and is likely exposed by recent changes to
bounding box calculation.

The missing check for DL_INDEX4 dates back to code from 2002 which
intended to check this but was checking for DL_INDEX3 twice
which got removed as part of a cleaned up.

This could be hidden from memory checking tools as meta-balls
over-allocate vertex arrays.

Cleanup: remove disabled code

Originally pointcache wasn't supported when the file wasn't saved.
Remove commented code as this hasn't been the case for a long time.

Fix T94082: Curve to point empty evaluated NURBS crash

This is basically the same as rBee4ed99866fbb7ab04, the fix is
simply to check if the spline has evaluated points when deciding
the offsets into the result points array.

Geometry Nodes: support instance attributes when realizing instances

This patch refactors the instance-realization code and adds new functionality.
* Named and anonymous attributes are propagated from instances to the
realized geometry. If the same attribute exists on the geometry and on an
instance, the attribute on the geometry has precedence.
* The id attribute has special handling to avoid creating the same id on many
output points. This is necessary to make e.g. the Random Value node work
as expected afterwards.

Realizing instance attributes has an effect on existing files, especially due to the
id attribute. To avoid breaking existing files, the Realize Instances node now has
a legacy option that is enabled for all already existing Realize Instances nodes.
Removing this legacy behavior does affect some existing files (although not many).
We can decide whether it's worth to remove the old behavior as a separate step.

This refactor also improves performance when realizing instances. That is mainly
due to multi-threading. See D13446 to get the file used for benchmarking. The
curve code is not as optimized as it could be yet. That's mainly because the storage
for these attributes might change soonish and it wasn't worth optimizing for the
current storage format right now.

```
1,000,000 x mesh vertex: 530 ms -> 130 ms
1,000,000 x simple cube: 1290 ms -> 190 ms
1,000,000 x point: 1000 ms -> 150 ms
1,000,000 x curve spiral: 1740 ms -> 330 ms
1,000,000 x curve line: 1110 ms -> 210 ms
10,000 x subdivided cylinder: 170 ms -> 40 ms
10 x subdivided spiral: 180 ms -> 180 ms
```

Nodes: Add vector support to Map Range node

This replaces lost functionality from the old GN Attribute Map Range node.
This also adds vector support to the shader version of the node.

Notes:
This breaks forward compatibility as this node now uses data storage.

Cleanup: reorganize doxygen modules

- Nest compositor pages under the compositor module
- Nest GUI, DNA/RNA & externformats modules under Blender.
- Remove modules from intern which no longer exist.
- Add intern modules (atomic, eigen, glew-mx, libc_compat, locale,
numaapi, rigidbody, sky, utfconv).
- Use 'intern_' prefix for intern modules since some of the modules
use generic terms such as locale & atomic.

Geometry Nodes: simplify using selection when evaluating fields

We often had to use two `FieldEvaluator` instances to first evaluate
the selection and then the remaining fields. Now both can be done
with a single `FieldEvaluator`. This results in less boilerplate code in
many cases.

Performance is not affected by this change. In a separate patch we
could improve performance by reusing evaluated sub-fields that are
used by the selection and the other fields.

Cleanup: Remove runtime uiBlock pointer from nodes

Code is simpler when the uiBlocks used during drawing are simply
stored in an array. Additionally, looping can be simpler when we use
an vector to hold a temporary copy of the tree's linked list of nodes.

This patch also slightly changes how uiBlocks are "named" in
`node_uiblocks_init`. Now it uses the node name instead of the
pointer, which is helpful so we rely less on the node's address.
