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

TSEvent: refactor and fix bugs, add TSSetPostEventStep()

See merge request petsc/petsc!6752

Implement setting two distinct post-event steps

The two post-event steps are managed by:
TSSetPostEventStep(), -ts_event_post_event_step,
TSSetPostEventSecondStep(), -ts_event_post_event_second_step

Implement setting two distinct post-event steps

The two post-event steps are managed by:
TSSetPostEventStep(), -ts_event_post_event_step,
TSSetPostEventSecondStep(), -ts_event_post_event_second_step.

(The latter function and option are replacement for the original PETSc
TSSetPostEventIntervalStep(), -ts_event_post_eventinterval_step,
with some change of overall behaviour of 1st + 2nd steps).

Also, reduce the number of tests ~ 4 times.
