Provide access to widget configuration from widget expressions

[florian-h05]

Fixes #1025.

This introduces a new object for component configuration expressions to access the configuration of the component itself.

After this got merged, I can provide the docs update as well.

Probably a good thing, but (I haven't tested or analyzed further) is there a possibility of infinite loops (if a config property contains an expression including config which would reevaluate the expressions in the config)?

[florian-h05]

I haven‘t really though about that this way, I will check if there is that possibility.

[florian-h05]

I have just checked this concern, in fact if you access a config property that contains some expression, the expression from this widget property isn't evaluated at all - which IMO is a good thing:

- component: oh-label-card
   config:
     title: =5+3/2
     footer: =config.title

Alright then!
