SNESLineSearch: add bisection line search

Add new bisection line search for SNES, which proves to be useful for highly non-linear problems. The line search assumes that F(X) = grad G(X) and seeks to find the root in the directional derivative through bisection.

Unifies all context destructors to have a form of PetscCtxDestroyFn == PetscErrorCode (*)(void **)

Changes the previous subset of destructor APIs that used PetscErrorCode (*)(void *) (mostly those that
used PetscContainer

- Now allows any context to be a PetscObject
- Will provide a cleaner mapping to bindings in other languages
- Simplifies the maintenance of PETSc source code; improves clarity

Not backward compatible, compiler warnings will tell users what functions need to be updated
