[data-shapes] Provide a var expression for (shnex:var) "value" in the context of property shapes (#644)

robert-david has just created a new issue for https://github.com/w3c/data-shapes:

== Provide a var expression for (shnex:var) "value" in the context of property shapes ==
A [var expression](https://w3c.github.io/data-shapes/shacl12-node-expr/#VarExpression) currently can be "focusNode" or a defined variable in the scope. It would be useful to also have the value available as a predefined var in the context of property shapes.

Motivation comes from a use case, see https://github.com/w3c/data-shapes/issues/560
I wasn't able to express the constraint without using shnex:var "value".
Also, [Example 21](https://w3c.github.io/data-shapes/shacl12-node-expr/#example-21) already shows such a use of "value".
