Previously the only way to control the subtype was to remove the group
input or output and create it again. This commit adds a dropdown to
change an existing socket, for supported socket types.

Based on a patch by Angus Stanton: https://developer.blender.org/D15715

It was necessary to fix the UI code slightly; the layout's context
wasn't being used in calls to an operator's enum items callback.

Thanks, seems to work in my test. The main issue I found is that the default and min/max values are reset when changing the subtype.

Almost there. Currently the subtype in the modifier does not update when I have it in the node editor. I think the issue is that the subtype stored in bNodeSocketValueVector is not updated now.
