[Feature Request]: Compound TYPE support on sockets

### Is there an existing issue for this?

- [X] I have searched the existing issues and checked the recent builds/commits

### What would your feature do ?

Allow different types to use the same socket. ComfyUI should only care that the socket says they can connect, not the data in it -- that is for the node.

### Proposed workflow

1. drag off a VEC2 and plug it into a VEC2INT
or
1. drag off a INT and use it as a FLOAT because the socket is (INT|FLOAT) type.

etc...
