How do we display expression properties

[nkylstad]

Description

A lot of properties can now be defined as either a static value or as an expression. F.ex:

• required and readOnly

These can now be set as true/false in our config view, but they can also be configured as an expression. If a boolean/expression value is set as an expression, the config will be disabled in the config panel, and inform the user in the help text

In addition, we currently only support boolean/expression type values. We should support all property types that can be either a static value or expression (string, number, etc).

When the user configures a component for the first time, should they be given a choice when it comes to this type of component? Or a link that takes them to the expression editor for that property? Should we integrate the expression editor directly with the property?

@altinnadmin kan du gi meg tilgang til denne tavla, så jeg kan jobbe med denne saken?

@nkylstad jeg trenger en kort forklaring på denne før jeg kan forslå tekster.
