Geometry Nodes: Random Value Node

This node replaces the deprecated Attribute Randomize node, populating
a vector, float, integer or boolean field with random values. Vector,
float, and integer have min/max settings, which are also field aware.
The boolean type has a probability value for controlling what portion
of the output should be true. All four types have a field seed input
which is implicitly driven by the index, otherwise, all values would
be the same "random" value.

The Random Float node is now deprecated like other nodes, since it is
redundant with this node.
