solidify_extrude_generaly working.

- working with data from node

- added basic support for input data

moved solidify to Blender Kernel

makeing node and modifier working with solidify kernel version.

adaptive_cloth: mesh: add empty elements

adaptive_cloth: mesh elements, better constructors

3D View: adjust order of planes for occlusion check

Move far plane last since it's the least likely to intersect edges.

Blender v2.93.1 release version bump.

Cleanup: fixed some issues with collision display and formatted the code
No functional changes

OptiX: select BVH build options from Scene params

Currently, the OptiX BVH build options are selected based on whether
we are in background mode (final renders) or not (viewport renders).
In background mode, the BVH is built for fast path tracing and low
memory footprint, while in viewport, it is built for fast updates.

However, on platforms without OpenGL support, the background flag is
always set to true and prevents using fast BVH builds in the viewport.

Now, the BVH options derive from the Scene BVH settings:
* if BVH is static, a fast to trace BVH is built
* if BVH is dynamic, a fast to update BVH is built

Cleanup: comment use C comment-blocks for GHOST_Types.h

Also use full sentences, and correct typos.

Cleanup: spelling

Cleanup: use early return for selection callbacks

Fix bone select failing with end-points outside the view

Apply the same fix for T32214 (edge-select failing) to bones
which also failed when their end-points were outside of the view.

- Add V3D_PROJ_TEST_CLIP_CONTENT support for edit & pose bone iterator
and use for selection operators.
- Remove unnecessarily complicated checks with pose-mode lasso tagging.
- Correct error in pose-mode LassoSelectUserData.is_changed
(currently harmless as it's not read back).

Cleanup: Use "size" instead of "points_len" in spline code

Previously this was mostly consistent, but not completely. It's helpful
to use the same name for the same meaning everywhere in this area.

Cleanup: Rename variables, use shorter names

`src` and `dst` are perfectly clear, and avoid repeating unecessary
characters when writing the variables many times, allowing more space
for everything else.

Added support for shape preserving cuts

UI: Sequencer: add refresh_all operator to all sequencer view menus

Update CacheFile comments.

Removed obsolete references to Alembic, as
the CacheFile code is now used for USD
archives as well.
