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

Plex: Fix DMSetCoordinateDisc() for isoperiodic boundaries

This reinstates the changes added in !5970 and removed in !6959.

tl;dr, `DMCreateInterpolation` (used in `DMSetCoordinateDisc`, and
`DMProjectCoordinates` before it) does not handle isoperiodic boundaries
correctly. !5970 replaced that code using `DMProjectFieldLocal` instead.
That was then removed in !6959. This is also discussed in issue 1506.
I initially made an MR in !7308, but that was on a fork. This commit is
on the PETSc repo itself.

Unifies all context destructors to have a form of PetscCtxDestroyFn == PetscErrorCode (*)(void **)

Changes the previous subset of destructor APIs that used PetscErrorCode (*)(void *) (mostly those that
used PetscContainer

- Now allows any context to be a PetscObject
- Will provide a cleaner mapping to bindings in other languages
- Simplifies the maintenance of PETSc source code; improves clarity

Not backward compatible, compiler warnings will tell users what functions need to be updated
