Geometry Nodes: Add default_value Property for Matrix Socket

The matrix socket in geometry nodes has no property display, meaning it can be only controlled by other nodes and not directly, and it can't be used in the modifier interface.

But a property display could be added, because there is a matrix subtype of FloatVectorProperty. Below is an image of what the matrix property looks like on a custom socket in the custom nodes template. matrix socket.png

This makes sense, I agree being able to diplay the matrix right on the modifier/node level without the need of an external node such as combine matrix would follow the same principle as the other value data types (float, integer, vector, boolean etc...) Just because Matrix is a long list doesn't mean it should always be hidden, your design proposition is really good in my opinion
