Add automatic generated fortran support for setting and returning contexts

Major cleanup of the code for setting and returning application (previously called user) contexts
- PetscCtx ctx is now the standard for passing in contexts
- PetscCtxRt ctx is the standard for passing out contexts, including context destroy routines based on PetscCtxDestroyFn

Both of these are typedef to void*

Also removed most use of user and userctx for context arguments now consistently named ctx

Improved documentation on PetscCtx and PetscCtxRt and on how to use contexts (including getting them) from Fortran

Change the `destroy()` function argument of `TSTrajectorySetTransform()` to type `PetscCtxDestroyFn *`. These means the destroy function must deference the argument before operating on it

TSMonitorWallClockTime: -ts_monitor_wall_clock_time

Sometimes machine performance experiences transient degradation and one
wishes to know about the elapsed wall-clock time. With implicit
integration, a given step could be slow because it needs more iterations
or because of a machine issue. Reporting the snes and ksp iterations for
each step is useful to distinguish these factors.
