This adds a boolean output for each of the menu items. The output is true, if
the passed in menu value is that item. This avoids the need to compare the
output value to the input values to get a boolean for whether a specific menu
item was passed in.
Support is added for Geometry Nodes as well as the Compositor. Usage/Value
inferencing has been updated as well.

Currently, `InferenceValue` contains either a primitive value or is in the
"unknown" state. Previously, all code had the assumption that when the value is
not unknown, it is a primitive value. However, that may not be true anymore when
we support inferencing through e.g. bundles and closures as those are not
"primitive". This assumption is removed now, non-primitive values have not been
added yet though.

Value and usage inferencing can be done independently. Usage-inferencing uses
the value-inferencing but not the other way around. Extracting value-inferencing
makes the separation more clear and also simplifies potentially reusing the
value-inferencing code later on.
