Curve Batch Cache: Fix issue with cd_used

cd_used needs to be the combination of generated data.

Mesh Batch Cache: Optimization & Refactor shaded surface support

This now only upload data per loops to the GPU, making use of index buffer
to draw polygon. This make use of the vertex cache, speed up renders
and saves a lot of vram.

Update performance is also slightly faster and can even be improved further
by updating only uvs or vcol independently.

This commits breaks texture paint batches. It will be added back in another
commit.

Fix T58652: Crash editing shape keys weirdness with instances

This is a second attempt to get the crash fixed. The original fix
worked, but it was reverted by d3e0d7f0825.

Now the logic goes as:

- All pointers which we can not have shared (the ones which are
owned by the runtime) are cleared.
- The rest of runtime stays untouched.

This seems to be enough to keep particles happy.

Remove some files restored in Game Engine

Most likely was caused by bad resolution of recent merge conflict.

Fix T59483: Grease Pencil Additive Drawing mode doesn't work with shapes

Eevee: Change Bent normal calculation

This changes the bent normal effect to be a bit more subtle.
I also tuned down the bent normal blending factor so mesh faceted look may
appear more in occluded regions. this is to increase the fidelity of the
indirect lighting. This blending might be a parameter in the future.

Based the calculation on "Bent Normals and Cones in Screen-space"
by O. Klehm, T. Ritschel, E. Eisemann, H.-P. Seidel

GPU: Add Intel HD Graphics 530 to the list of buggy intel gpus

Workbench: Use int to fix compilation issues on certain platform

Context: add objects_in_mode(_unique_data)

Needed for Python to easily support multi-object edit/pose modes.
