Material Function Input Displays Incorrect Data Type for Volume Texture, Static Bool, Material Attributes, and External

The material function Input Displays incorrect data type for Volume Texture, Static Bool, Material Attributes, and External. The function will still work properly however the type data is displayed incorrectly on the node.

Working as expected in 4.19 CL# 4033788
Found in 4.20 CL# 4233996 and 4.21 CL# 4299102

This is a regression.

1. Create a material function
2. Add an input node
3. Set the input type to Volume Texture, Static Bool, Material Attributes, or External

Results:
The input type shown on the node will be incorrect

Expected:
The input type would shown would be correct
