[UE Material] Implement angle gradient material and checkerboard texture material

Target

step

1. Angle gradient material 

1. First, separate the R and G channels of the "Texture Coordinate" node through the "Mask" node.

2. Map the range 0~1 to -1~1 through the "RemapValueRange" node

You can see the R channel effect at this time:

 G channel effect:

Continue to add the following nodes

2. Checkerboard texture material
