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

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 `lib\tests\modeling`
{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:
-`lib\tests\modeling\geometry_nodes\mesh`
-`lib\tests\modeling\geometry_nodes\points`
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 path\to\blend\file --python path\to\geo_node_test.py`

MeshTest now compares selection between evaluated mesh and expected mesh. This way, we can test more operators
such as `faces_select_linked_flat`
Note: selection comparison intentionally does not happen in BKE_mesh_cmp() on C side but rather on Python side, because
selection is independent of mesh generation.

This revision contains the following changes-
- Updated the existing testing framework for Modifiers for Regression
Testing.
- Tests for Physics modifiers and remaining Generate and Deform modifiers are added.
- The existing `ModifierSpec` is updated with backward compatibility to support Physics Modifiers.
- Now there is support for frame number and giving nested parameters for attributes.
- Some Deform modifiers required Object Operators, e.g. "Bind" in Mesh Deform, so a new class was added to support that functionality.
- A separate class for holding Particles System, they are tested by converting all the particles to mesh and joining it to the mesh they were added.
- Updated the format to add tests for Bevel, Boolean and Operators as
well.

This uses the same framework as automated modifier tests. It adds a physics
modifier, bakes and compares vertex coordinates on the end frame.

Submitting on behalf of Jesse Y (deadpin).
In test harness for modifier testing, now run mesh validation
on output mesh. Also, fix printing so it interleaves properly.
Patch from Habib Gahbiche (zazizizou) moves the "run operator and
compare mesh to a golden" paradigm used in bevel and boolean tests
into a general framework that separates the test specs from the
blend files. Then adds some other operator and modifier tests using
the new framework. Diff D5357.id20724.diff was applied.
New .blend files, modifiers.blend and operators.blend are needed
in the tests/modeling svn directory; those were separately committed.
