Nodes: store socket declaration reference in socket

Previously, to get the declaration of a socket, one had to go
through `node->declaration`. Now this indirection is not necessary
anymore. This makes it easier to add more per-socket information
into the declaration and accessing it in various places.

Currently, this system is used by socket descriptions and node warnings
for unsupported geometry component types.
