Only regenerate outdated files of the debug datapack

[Adrodoc]

Currently the whole debug datapack is regenerated for any change to a function or breakpoint. This is especially bad because stepping dynamically adds and removes breakpoints, causing a regeneration each time.

When breakpoints are changed, we only need to regenerate the files of the function those breakpoints are in and resume_self.

When a function is changed we need to regenerate the files of that function and if the call tree changes also the return functions.
