Geometry Nodes: Implicit conversion change for float/int/color to bool

Change `float to boolean` and `int32 to boolean` to return false for zero and negative values.

This aligns with how artists would expect these values to work. This is in contrast to what a coder would expect. It was determined on blender.chat that this was a better default. This means that a negative float value would give a boolean false.

Change `Color4f to boolean` to return false for zero and negative grayscale values.

Likewise, for color to boolean, to account for negative value colors, the grayscale value would be used for determining if a colour was false or not.

Fix T86894: Geometry nodes drag and drop creates a duplicate node

Added a condition to the poll so that it ignores drag and drop on the button. The Paste Name operator is just not implemented. Doesn't work for shading nodes either.

Nodes: Add Refract and Faceforward functions to Vector Maths nodes

Cycles, Eevee, OSL, Geo, Attribute

Based on outdated refract patch D6619 by @cubic_sloth

`refract` and `faceforward` are standard functions in GLSL, OSL and Godot shader languages.
Adding these functions provides Blender shader artists access to these standard functions.

Nodes: Add support to mute node wires

This patch adds the ability to mute individual wires in the node editor.
This is invoked like the cut links operator but with a new shortcut.

Mute = Ctrl + Alt
Cut = Ctrl

Dragging over wires will toggle the mute state for that wire.
The muted wires are drawn in red with a bar across the center.
Red is used in the nodes context to indicate invalid links, muted links and internal links.

When a wire is muted it exposes the original node buttons which are normally hidden when a wire is connected.

Downstream and upstream links connected using reroute nodes are also muted.

Outside scope of patch:
- Add support for pynodes e.g. Animation Nodes
- Requires minor change to check for muted links using the `is_muted` link property or the `is_linked` socket property.

Geometry Nodes: Implicit conversion add int to color

Add implicit `int32 to Color4f` conversion. Matches `int32 to float3` conversion logic.

This may not be the most useful conversion but prevents an error in the Attribute Convert node.

Geometry Nodes: Implicit conversion change from distance to average

Use average instead of distance when converting from float3/float2 to float. This matches behaviour of shader nodes.
