bitbake: build/ast: Create strong task add/del API in bb.build

Currently its near impossible to control task addition/deletion from
metadata context. This adds stong add/deltask API to bb.build
which is traditionally where it resided. The rather broken
remove_tasks function was removed, it didn't appear to do anything
useful or have any users.

This allows us to clean up hacks currently in use in metadata and use
standard API for it instead.
