Fix potential buffer overrun in drw_shader_dependencies_get

Logical error let this function to write one past the buffer bounds.

Nodes: Add a callback to check for valid socket type

This adds a callback to bNodeTreeType to check which socket types are
valid for the tree type. Function has been implemented for the normal
tree types, and can be implemented for custom node trees with python,
by adding a `classmethod` to the tree. However, only builtin socket
types are supported.

This is relevant for T87049, but it also has the advantage that it is
now clear which node trees support which sockets. Previously this
was assumed to be known by all developers.

Geometry Nodes: Add a template utility to mix two attribute values

This is just linear interpolation, but it's nice to have an equivalent
to `mix3` for only two values. It will be used for interpolation of
values between bezier spline control points.
