Regression Testing: Running tests based on blend files

Runs tests based on blend files with minimum python interaction.
Developed as part of GSoC 2021 - Regression Testing of Geometry Nodes.
Earlier, tests were built from scratch by adding a modifier/operation
from the Python API.
Now, tests can also be created inside blender and are compared using
Python script.

Features: Automatically adding expected object if it doesn't exist.
This patch adds tests for the following Geometry Nodes category:
* Curves
* Geometry
* Mesh
* Points

The implemented UML diagram for refactoring of mesh test framework.
{F10225906}

Technical Changes:
SpecMeshTest: It adds the modifier/operation based on the Spec provided.
BlendFileTest: It applies already existing modifier/operation from the blend file.

Test folders hierarchy with tests. This folder should be extracted to `libtestsmodeling`
{F10240651}
Note: The `geometry_nodes` folder might lie under another `geometry_nodes` folder while extracting, please double check. Use the inner-most one.
The hierarchy should be:
-`libtestsmodelinggeometry_nodesmesh`
-`libtestsmodelinggeometry_nodespoints`
and so on.

* From `ctest` the tests should be run as `ctest -R geo_node -C [Configuration]` on Windows.
* Each single test can be run with its entire name e..g `ctest -R geo_node_geometry_join_geometry`.(just an example). Run `ctest -N -R geo_node` to see all tests.
* From blender, the tests can be run `blender -b pathtoblendfile --python pathtogeo_node_test.py`

Remove the code in `BKE_collection_move` to preserve LayerCollection flags.

This code was actually buggy (forcefully re-enabling excluded layers in some
cases).

Further more, it should not be needed now that layerCollection resync code
reuses as much as possible existing layers instead of deleting and
re-creating them all the time.

Fix T89415: update multi input indices after deleting a node

When deleting a node, links attached to that node are deleted, but if one
of those links was connected to a multi input socket, the indices of the
other links connected to it were not updated. This adds updates both in
the case of a normal delete as well as after a delete with reconnect.

PyAPI: support different int sizes for PyC_AsArray

Added YAML builtbot config file.

Builtbot is switching over from json to yaml. Both
configuration files should be kept in sync for now.

The json file will be removed when everything works as expected.

Cleanup: Fix build warning

Cleanup: Remove unnecesary undefs

Macros `SEQ_ALL_END` and `SEQ_ALL_BEGIN` no longer use `seq->tmp`.
Therefore they are safe to use regardless from where they are called.

VSE: don't snap by default

Snapping by default goes against convention, so this setting was
re-evaluated. Also snapping by default can conflict with new image
transform system, see T90156

There wasn't consensus, so disable snapping by default to follow
established convention.

PyAPI: add multi-dimensional array conversion utility functions

Add array conversion functions that take dimension arguments.

- PyC_AsArray_Multi (version of PyC_AsArray).
- PyC_Tuple_PackArray_Multi_* (version of PyC_Tuple_Pack_*).

Anotations: Fix a several issues with stroke placement

Previously, this option was not exposed in the UI, only for the clip editor.
There were also multiple rna properties that did the same thing for each of the 2D editors.

There was also an issue where the property enum items were the same as the 3d view which didnt make much sense.
