event/ast: Add RecipeTaskPreProcess event before task finalisation
There are various pieces of code which need to run after the tasks are finalised but before bitbake locks in on the task dependencies. This adds such an event so dependency changes in anonymous python can be accounted for and acted upon by these specific event handlers.
