This expands Cycles' support for handling OSL property metadata for
Custom camera parameters and translating it to Blender's UI.
Specifically, it adds support for:
- Translation inputs (`string vecsemantics = "POINT"`)
- Normal inputs (`string vecsemantics = "NORMAL"`)
- File inputs (`string widget = "filename"`)
- Angle inputs (`string unit = "radians"`)
- Distance inputs (`string unit = "m"`)
- Time inputs (`string unit = "s"` or `string unit = "sec"`)
- Enum inputs (`string widget = "mapper", string options = "left:0|right:1"`)
It also sets the default value correctly, and corrects a warning string to
also mention cameras in addition to nodes as possible users of OSL shaders.
