Before this commit, the rendering context of kanban and form views
was the instance of the KanbanRecord and FormRenderer, respectively.
As a consequence, a lot of implementation details (e.g. "props",
"__owl__", any Class method...) were available. This wasn't what
we want.
The door being left open, people went through, and in 16.0, several
kanban and form archs contain(ed) such use of undesired "features".
With this commit, we restrict the rendering context of those two
views. In kanban views, it contains what has been historically
available (e.g. "record", "widget", "kanban_color"...). In form
views, nothing is available since the only dynamic part in those
archs is the attrs, which aren't evaluated by the rendering engine.
To do that, we use `t-call-context` owl directive. When using this
directive, the rendering context is the given one, + `this`. So the
component instance is still available, but through the `this`
keyword. We can thus use it in our compilers, to make them work as
before. Note that `this` can never be used in an arch directly.
