Implement PetscBT with new PetscByte datatype as unsigned char

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

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

Fortran 90: fully embrace After 34 years!

- deprecate use of 'F90' in Fortran function names
- use Fortran pointers when appropriate
- the new Fortran API is not backward compatible with previous versions!
- also clean up inconsistent PETSc code detected by new Fortran generation tools
- drop use of bfort
- automatically generate all the Fortran PETSc objects, enums etc from the include files
- generate most of the Fortran interface definitions and functions from the source code
- simplify the number and organization of Fortran modules
