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

Fixes doc and behaviour of an unset -options_left value as reported in #1834.

Closes #1834

See merge request petsc/petsc!8905

Fixes doc and behaviour of an unset -options_left value as reported in #1834.

Now, `-options_left` and `-options_view` are independent.

use standard bool instead of enum

PetscBool is equivalent to _Bool/bool in C

For C standards prior to C23, true = 1 and false = 0 are defined in <stdbool.h>.
For C23, true and false are real keywords.

The Fortran equivalent is logical(C_BOOL) with C_BOOL from
ISO_C_binding.

The C and the C++ standard do not specify the size of Booleans, but they
typically have a size of 1 Byte with b00000000 for false and b00000001 for true.
When using compilers from the same vendor, it is sane to assume that
_Bool/bool in C and bool in C++ are fully compatible. But that is not
guaranteed by the standards

Better mismatched MPIU_Allreduce error diagnosis

See merge request petsc/petsc!8586

Sys: better mismatched MPIU_Allreduce error diagnosis

If allreduce mismatches at different code lines, better to print out the line numbers on all processes (vs. rank 0) for diagnosis.

In addition,

Sys: better mismatched MPIU_Allreduce error diagnosis

If allreduce mismatches at different code lines, better to print out the line numbers on all processes (vs. rank 0) for diagnosis.

In addition, line numbers are good enough, we don't need to check petsc functions (if functions are different, lines are defintely different)

Use a function instead of inlined macros to save stack space in PetscLogHandlerView_Default_Info(), where MPIU_Allreduce() is called many times.
If with inlined macros, we encoutered __chkstk segfault in PetscLogHandlerView_Default_Info() with mswin-mpiuni.
