injection_points: Add variant for injection_point_attach()

This new function is able to take in input more data than the existing
injection_point_attach():
- A library name.
- A function name.
- Some private data.

This gives more flexibility for tests so as these would not need to
reinvent a wrapper for InjectionPointAttach() when attaching a callback
from a library other than "injection_points".  injection_point_detach()
can be used with both versions of injection_point_attach().
