Cleanup: type conversion warning

Fixed typo Python API

`mathutils.geometry.barycentric_transform` used `tri_a[1-3]` for the
target triangle, but in fact they are `tri_b[1-3]`

Fix ugly recursive pattern in RNA PointCache data layout.

PointCache was having a collection of items of PointCache type, having a
collection of items of PointCache type, having...

Nuff said.

For now, chose the 'ugly' way to fix it, that is, the one that changes
nothing to API and scripts using it: we define another 'PointCacheItem'
RNA type for items of our point cache collection, which has exact same
interface as PointCache except for the collection.

This is doomed to be rewritten at some point anyway, not worth spending
time trying to define a really correct data layout for now.

CMake: disable boost for lite builds

Cleanup: kdopbvh, only set parent nodes once

Cleanup: use MEM_SAFE_FREE

mathutils: replace interp w/ blend when standalone

build_environment: remove msvc compiler warning from boost.

Even the boost people have given up trying to keep up with the rapid release
of new msvc versions, and have removed the warn for now see: https://github.com/boostorg/config/commit/5ad0730630188b55e2ee554dec53b5498fc0a030#diff-eac863c1d46c77471e54e8818aab7534

MSVC: ignore warning c4828 The file contains a character that is illegal.

The only place this warning is coming from is from comments in headers of 3rd party libs. we can safely repress this warning for now.

Eevee: Volumetrics: Fix crash when using smoke volumes.

DRW: Fix error in texture binding / unbinding.

GWN: Element Buffer: Refactor / Optimisation.

- Upload the data to the GPU directly when creating the element buffer in
GWN_indexbuf_build_in_place().

- Convert data in place when squeezing the indices and removing the need
for another allocation.

- GWN_indexbuf_build_in_place() can be used with already used element
buffers and reupload their data without changing vbo id (keeping vaos
up to date).

DRW: Move cache time to GPUViewport for profiling

This enables us to average this timer over time like the others.

GWN: Vertex Buffer refactor.

We now alloc a vbo id on creation and let OpenGL manage its memory directly.
We use glMapBuffer to get this memory location.

This enables us to reuse and modify any vertex buffer directly without
destroying it with its associated Batches.

This commit does not really improve performance but will let us implement
more optimizations in the future.

We can also resize the buffer even if this can be slow if we need to keep
the existing data.

The addition of the usage hint makes dynamic buffers not a special case
anymore, simplifying things a bit.

Refactor: Collada: remove param, changed order of params in Function call

* In the Collada Module parameters are typically ordered
in a similar way. I changed this to:

extern std::string get_joint_id(Object *ob, Bone *bone);

* The Object parameter was not used in get_joint_sid().
I changed this to:

extern std::string get_joint_sid(Bone *bone);

Fix (unreported) a broken 'RNA diff collection' case.

When a name property is defined for collection's struct, but no name is
actually set, we want to also fallback to index case. We cannot handle
empty names to address items of a collection!
