Geometry Nodes: Add Attribute Curve Map Node

This node has the same functionality as the color and vector curve
mapping nodes in the shader editor. Here is works on every value for
the selected attribute, and it can also output a float value. Other
than that, the implementation is quite straightforward-- almost
completely boilerplate code.

Geometry Nodes: Add an "Auto" option for Attribute Convert data type

Currently there is an "Auto" option for the domain, this commit adds a
similar option for "Auto" data type, that uses the data type from the
target attribute or the source attribute (in that order).

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.
