PCSetUpOnBlocks_FieldSplit_Schur(): fix memory leak

Fix the inconsistent usage of #if [!]defined XXX compared to defined(XXX)

Thanks-to: Pierre Jolivet

An LLM Claude detected the incosnsitency it was not used to remove the inconsistency

Remove the last of the use of horizontal lines --- as seperators. With modern code development systems they are not needed and just an eye-sore

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

PCREDUNDANT: remove explicit inner KSPSetUp()

If the inner PC is setup at this point in the code, then:
- during the outer solve the setup is called again resulting in two constructions of the same preconditioner
- it is impossible to change the parameters of the PC before the setup using low-level API
