[chip-tool] Add Nullable supports in test value expressions

[vivien-apple]

Problem

The window covering test suite uses a Nullable value into an expression that validates some test results.

Change overview

• Add supports for chip::Nullable into expressions

Testing

The test runs but it is failing for now as there is a bug in the window covering cluster. This is why it is disabled. @jmeg-sfy will turn it on soon.
