$getPropKey method
The base implementation for UiPropsSelfTypedExtension.getPropKey
,
which wraps this with better generic typing, since we can't generically express
the type of the current class in this declaration.
UiPropsSelfTypedExtension.getPropKey
and thus this method are necessary to be able to
implement utility methods for safely accessing props, such as
UiPropsSelfTypedExtension.getRequiredProp
.
