Add point and line shaders

[aparajit-pratap]

Purpose

DYN-2702, DYN-2707

This PR includes the following changes:

1. Replaced assignment of colors for the different states (selection, isolation, frozen, etc.) to points and lines with shaders
2. Added 3 new shaders - pixel shader each for point and line and one common vertex shader for both
3. Enabled line/curve geometry selection
4. Added the default helix geometry shader pass for both point and line rendering
5. Using the FadingNearDistance property on the helix builtin PointMaterialCore and LineMaterialCore types to pass state data to the shader
6. Added new common DynamoPointLineRenderCore class for both DynamoPointGeometryModel3D and DynamoLineGeometryModel3D to override the required helix RenderCore class
7. Added common DynamoRenderCoreDataStore class to manage state information for all geometry types - mesh, point and line
8. Updated local copy of common helix shaders used by our shaders from helix-toolkit version 2.11
9. Updated image comparison baselines images for points, lines
10. Deleted WPF visualization tests related to point and line vertex colors that are no longer relevant

@aparajit-pratap this looks great! - Much simpler than before!
Did you need to update those image tests?

I found that I need to update just 2 of them. Found only those 2 to be failing. I am double-checking.
