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

Finish converting the function prototypes of destroy for contexts to use PetscCtxDestroyFn

The goal of all the commits in this MR is to unify the destruction of "application" contexts.

This will help with supporting language bindings. For example, for Fortran the application context
would be a user derived type

Fix prototype of DMShellSetDestroyCtx function argument to use PETSc standard way of doing it with PetscCtxDestroyF.

Also fix PetscViewerGLVisSetFields prototype of destroy function

These two locations were missed when PetscCtxDestroyFn was introduced as the universal function prototype for context destruction in 3.23
