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

some doc/manual page fixes

TS Hamiltonian ex2: Lots of monitoring
- Add cell velocity distribution monitor
- Add Fourier Transform monitor
- Fix output file names
- Add field energy calculation
- Add field averaging

ts: EvalTimes only if TS hasn't failed

This will prevent the worktol PetscCheck from triggering before the
actual solver divergence can be returned to the user.

TSTHETA: must check domain error when theta != 1 after assembling solutio

TS tests ex2: test for BDF_1 == BE

fix for undefined value
fix broken parallel case

TSBEULER: can directly copy the solution of the nonlinear step

TSTHETA: match scalars with BDF in LTE evaluation

TSBDF: do not take half step for backward Euler

make: add explicit '% : %.c' target so that LINK.c target is in sync with LINK.F target '% : %.F90'

with multiple source compile into a singe binary:
- fixes Fortran example build: currently broken,

make: add explicit '% : %.c' target so that LINK.c target is in sync with LINK.F target '% : %.F90'

with multiple source compile into a singe binary:
- fixes Fortran example build: currently broken, due to duplicate obj-files in link command
- can now use consitent obj file dependencies irrespective of C-main or Fortran-main sources
- cab avoid duplicate compiles of same sources [esp with SEPARATE_COMPILE_LINK=1]

Merge branch 'jrwrigh/tssetevaltimes' into 'main'

ts: Add TSEvaluationTimes

See merge request petsc/petsc!8144

ts: Deprecate TSGetTimeSpan and TSGetTimeSpanSolutions

Also rename TSGetEvaluationTimesSolutions -> TSGetEvaluationSolutions

Co-authored-by: Barry Smith <bsmith@mcs.anl.gov>

CUDA: include <nvtx3/nvToolsExt.h> in newer CUDA

style: Change tspan -> eval_times

This to make the backend nomenclature more consistent

ts: Create TS*EvaluationTimes() functions

Plex+PetscFE: Fixes to allow embedded manifolds
- Add PetscFEGeomMode to describe geometry
- Reorganized PetscFEGeom
- PetscFEGeomCreate(), DMFieldCreateFEGeom() and DMSNESGetFEGeom() now take the PetscFEGeomMode
- J and invJ have dE dimensions
- f1, g1, g2, g3 have dE dimensions
- FIX the dim argument of all point function is really dE because it is used to index the gradients
- Clarified behavior of PetscFEGeomGetCellPoint()
- Now -dm_plex_coordinate_dim can change the coordinate dimension of a mesh created by Plex
- Implicit cell geometry must be used when dim != cdim
