Fix T89260: Eevee crashes with custom node sockets.

Cause of this issue is that Custom Node Sockets info type was
initialized as SOCK_FLOAT when registering. Areas within the core that
would ignore custom socket types by checking its type would use the
socket as being a float type.

When custom node sockets have a property called default_value blender
tries to store it as an internal default value what failed in debug
builds.

This patch will set the socket type to SOCK_CUSTOM when registering a
custom socket type and allow, but skip storage of custom default values.
In this case the default values should already be stored as custom
properies.
