[icons]: iCa icon using different naming conventions

[vpicone]

This came up during the icon library component work. The iCa-3D icon should be 3D-iCA to be inline with the other 3D Watson Health icons:

- 3D-Cursor
- 3D-curve--auto-colon
- 3D-curve--auto-vessels
- 3D-curve--manual
- 3D-MPR-Toggle

It should also use a more appropriate friendly name.
Suggesting 3D iCa to replace I ca 3D.

Other Watson Health friendly names:

- 3D Cursor
- 3D curve auto colon
- 3D curve auto vessals
- 3D curve manual
- 3D mpr toggle
