Revert^2 "hidden_api: Call back into libcore on hidden api detection""

This reverts commit bbe60d58496991c16e2943e174e26ab8a096b3d0.

This CL deviates from the approach of the original change. Instead of
calling back every time ShouldBlock.. was called, we explicitly call
back in cases where it's safe to do so.

Note that we only call back on reflective accesses for now, and not
link time accesses. Coverage for the latter will be added in a follow up
change.
