QML: Special case null as binding type
This gives us the opportunity to map the JavaScript null to QVariant's
concept of isNull().
[ChangeLog][QML] Assigning JavaScript null to incompatibly typed
properties generates a compile error now, rather than a runtime error.
Fixes: QTBUG-72098
Change-Id: I72fd1c30d84128c774230eaaea10455b2a0e064c
